seo suggestions for local computer repair website [baltimore, md]

Hey guys, i recently started my own business. I have created a website for computer repair in the Maryland region. monksystems is the name of the company, you can find it if you google it (unable to post links obviously). I would love to get 1st or 2nd page presence eventually for keywords "computer repair Baltimore", "Baltimore computer repair", etc.

So far for back-links i have...

1. Created a facebook, twitter, google+ (not many friends/likes yet, will work on that)
2. Registered for google places, yahoo places, angies list, merchant circle, brown book, etc...
3. Basically checked out each competitor on alexa and signed up on every site they had back links from

So far for keywords i have...

1. Made sure "computer" and "repair" are at the top of the list in terms of density with "Baltimore" soon following.

Any more suggestions? I just need someone to point me in the right direction of where to go next. Black hat suggestions are more than welcome.

I had a client in this niche, best thing you can do is find a 'directory' for computer services and get your listing with them. If you look at some other cities for your service and analyze the top companies, you'll find a few of these directories.

Focus on your 'brand' more than exact kw anchors, looks like you are well on your way. Good luck.
