Here's how I'd start:
- Start with the website, optimize it for conversions and lead-gen (lots of contact forms and buttons that are big, bright, and look good). Remember, big text and big buttons sell.
- Head over to Google Places and apply via the mail method for confirmation.
- Article creation, copy-writing for the company based on their niche.
- Directories (free local business listings).
- Article syndication (directories, guest posts, etc).
- Hit those syndications with a link wheel for backlinks.
- Create quality backlinks via finding good sources to drop backlinks (aka don't go to Fiverrr).
- Classifieds with backlinks to their site and a direct contact email for sales.
- Get them started with an offline campaign, pizza boxes, street team cards, etc.
- Mobile optimize for the QR Codes you dropped in the last step.
- Social Media, build up some profiles, get some momentum moving so they at least have a presence that validates them.
- Video anyone? Show how easy it is to install Direct TV, what kind of channels are available.

And that's just to start, without getting creative... :-P

Yup, I think Clarlkent covered pretty much everything you need to do to help them out get more leads. Google Places is a great place to start as they serve a local area and a proper listing well optimized can get you fron page of google in weeks humm well maybe months as your niche is competitive but from there is just expanding to the 4 must have, Facebook, Twitter, Youtube and linkedin to build all your social media.

Maximize the use of social media sites. SEO can help a lot on that.

Also, while you are working on the methods above, you might consider Adwords for them as well if they have any money to spend on it. They could start getting leads ASAP while you do SEO work over time.

I'd go with some PPC, if it is in their budget. Or if you are making a large enough profit from the client maybe you could invest some it into paid traffic. For me, there's nothing more fast or effective.

I had a suggestion for you nothing but go for local search engine i.e, lookonet.com/ which will really help you in solving your problem.
Good luck.
