Sam, the Internet is competitive, but there is place for everyone. It doesn't cost much to try, you are looking at perhaps up to $100 for startup expense altogether, while the long-term result could be more profitable.

I actually thought about the same idean before (I had the domain for it), but decided to use the domain for another concept which is more in line with other sites I run.

As the saying goes, it doesn't hurt to try.

Best,
