Hello My Friend,
You definitely have a GREAT idea simply because NO ONE in your area is doing this and it has proven to work in other areas.
I did this exact same thing with a former partner of mine but we also did a newspaper in eddition to the web-site. This thing sold like wild fire, which also gave us a medium to sell our own cars at a profit.
At the time, we were the only ones in the area doing this business and it was a HIT!
Now....here's what happened.....
A major car advertising company moved in on our territory and offered to buy us out. We sold it at a nice little profit and moved on to the next marketing idea.
The name of our company was Karz Weekly!
Good Success!!!!

Computers will always be a GREAT business, just like cars and real-estate.
P.S. I would look into promoting a newspaper in conjuction with the web-site. If not, I would use mini flyers to advertise the web-site and signs like the ones at

P.S.S. I would also contact radio stations and see about doing interviews. After all, you are the guy that found the used car solution.
P.S.S.S.If there is high unemployment for your area, an internet business is also a news worthy story.
