Heck, it'd be pretty nice if they approached you, wouldn't it?
Here's a little trick that will make both of those happen...
A bit of a warning: I'm going to give you the WHAT to do, and less of a how to do it. The reason is, I don't want you to get overwhelmed when there is no need to.
If I wrote out every step to this it would look really intimidating, when really most of it is a click here and a click there and you're done...
Now, here's what you're going to do.
You can do this in Facebook or GDN (Google Display Network) for cheap, so I recommend using both for maximum impact.
Seriously, we're talking pennies a click here.
First thing you need to do is create a few banners and write a few ads that promote you and what you do. (Go to Odesk if you can't make your own banners.) Be sure to write these as benefits for your potential clients. Your ads should be about how you're going to help them - not self aggrandize you.
Next start GEO-TARGETED campaigns in Facebook and GDN. Target the area you're willing to work and travel in. Don't pick keyphrases in GDN because you want to be seen by everyone in your area.
In GDN load up your banners, and set your campaign for any placement above or below the fold - you're only paying for clicks so it doesn't matter where you show up... In fact, you want to show up as many places as possible so people see your banners with your good looking mug on it.
In Facebook you can set your campaign to CPM to get the maximum views. Again, your picture should be your face. You're doing this to become a recognizable face after all.
(With the new Newsfeed ads - you have to do those in a PPC setting, but that's OK. It's still cheap and will get lots of views).
Once you've got your campaigns set up with your banners that have a picture of you in it - it's time to direct them to your site.
Personally I like to have a direct response style site that get's people to leave their contact info and what they need help with - but whatever site you have will work.
The important thing is you have re-targeting set up on your site!
Again, don't get bogged down with the "how" at this point. Adding a retargeting pixel to your site is a simple copy and paste.
So what have we done?
You've created 2 campaigns that will make you highly recognizable and instantly famous in your town.
And for those people who are interested in what you offer, they'll click your link, go to your site and be re-targeted around the web.
So if they didn't fill out your contact form, or take some kind of action on your site, they'll see you everywhere they go until they do
If you use Perfect Audience, AdRoll, or GDN's own targeting - you're going to have a very wide reach so no matter where they go - there YOU are.
Congratulations. Everyone in your area now knows your face. Expect to get a lot of "Do I know you from somewhere?" comments. And when you do, be sure to tell them what you do to help local businesses.
Oh, and did I mention - you can charge a fee to do this for local professionals who want to gain exposure?
