HELP!

I need to find a cost effective host for about 3 gigs of HD space and about 45 or 50 GB bandwidth per month. Its for a site that will make me NO money. It is TO-Center.com, a resource for custom maps and other stuff for the Tactical-Ops MOD for Unreal Tournament. I realize that I will be spending some cash, I just want to get the best for my money.

Any advice?
