Forget the free vidya games one, the internet in full of this stuff already.
I actually like WholesaleCompanies. I used to sell physical things online and I was always trying to find info on wholesale companies. I think it would be a great name to develop into a directory. eBay ads and other marketplace ads would make perfect sense on the site.
I'm not going to put a dollar value on these because they need to be developed.
Best of luck!
