Dominating Local Search, Youtube and Classifieds... What Else Can I do?

I'm at a point where lead flow is fairly consistent now, and if I can increase my lead flow just a little bit more, I can really start to scale things the way I want and hire more salesmen.

This is for an offline / home improvement niche.

I still have a lot of room left to dominate local search directories, gain even more prominence in google+, and target more keywords on youtube.

Although Craigslist seems to be at saturation point, in terms of gaining more exposure.

The reasons I love local search, youtube, classifieds, is because I'm a cheap *******. I'm pretty sure I've said this before.

I LOVE doing A LOT of work early on, in a way where I can sit back later, and have "free" leads come in. Craigslist is my largest expense right now, and my expenses for youtube/local search have dropped basically to nothing.

So my question is, WHAT ELSE can I do? I'm greedy. Its a neverending addiction to get more and more leads, as many as possible for as cheap as possible.

My thoughts are to do this:

1) Amp up/dump money into SEO to get more pages/terms from my site ranking.
2) Invest in PPC once I'm ranking better, in hopes of dropping my adspend.
3) Facebook? Maybe PPV, or paying someone to post cool content all day?

I'd prefer to stay way from direct mail. Because customer aquisition costs online have been extremely low (at least between local search and youtube, my costs have dropped down to essentially nothing like I've said).

So what are some other good long term strategies for getting super duper cheap traffic/leads?

Like I said, my mindset here is low cost marketing. I have no issues with spending money to get leads, but I think its the biggest mistake that most business owners make. Like "instead of taking the time to dominate local search the right way... I'll just blow money on PPC". I hate that type of mindset. I'm like the opposite of an instant gratification seeker if that makes sense.

Should I just continue building my prominence up in local directories like yelp/yellow pages/yahoo/bing local/insider pages/super pages etc? I've taken a break for a couple months and leads continue to come in. But I'm thinking it would be smart to really try capitalizing on them... and other listings that I've ignored like merchant circle/citysquares and what not.

I think the problem is my overhead has dropped significantly, so I'm tempted to start blowing money... rather than really capitalize on whats dropped my overhead the most.

What do you guys think?

Its kind of a confusing post but if the goal is dropping overhead/getting as many leads as possible... what is the best long term strategy?

I've made it this far w/out spending a dime on PPC, and love it. I still pay to get 700 ads posted every week on CL, and thats like my only real marketing expense right now. But these are ads I've been testing for over 6 months, so I get a massive ROI at this point. Lots of time/energy upfront, and now its paying off.

PPC will put a huge dent in my overhead, since its something I haven't taken any time to become proficient in. Even if the goal is outsourcing PPC, I would still need to become proficient in it, and that could take a lot of time. I'm smart enough to know that PPC is a huge beast to take on, and wouldn't even consider outsourcing anything until I understood all the magic it takes to make it work. I'm not sure what will give me the most bang for my buck. I feel like since I'm dominating google searches fairly well w/out PPC, it wouldn't really add that much to my funnel.

I'm not even sure SEO would tbpo.

I feel like prominence in all local search directories should continue to be my main focus. As long term, it provides an incredible ROI.

Youtube will also continue, as that provides me a great ROI.

CL will continue, but can't really be improved upon right now.

SEO will add to my overhead, and I already have tons of youtube videos ranking and google places ranking organically for more competitive keywords. But I still feel like SEO should remain a top priority, if anything to reduce PPC adspend when/if I decide to do it.

Then there is social media which I've barely touched on like facebook/twitter. I've ignored them because I just don't feel like these people are in a buyer mindset. But I'm thinking a combination of PPV and testing crazy ads may provide a worthy ROI with enough testings.

I'm basically trying to build the "ultimate low cost funnel".

Where I have the lowest overhead possible.
I came into marketing EXTREMELY paranoid about messing things up, so this mindset has served me well as a newbie, up untill this point. And now I'm wondering what the big deal is, maybe this mindset is actually limiting me?

I'll be honest, I have lots of money to blow, and thats whats freaking me out the most. I'm afraid I'll blow it now with any dramatic changes just because I can.

This post probably doesn't make a lot of sense, because there are too many critical details missing. Like what my current funnel actually looks like, what keywords I'm getting traffic for. But I'm just looking for a vague long term approach for keeping my overhead as low as possible, while increasing lead flow.
