obviously when more users come in in time the earning will increase, there is the option to add popups for extra earnings, but i just don't like popups
The server i currently use only cost me $130 per month!
The users are increasing gradually daily!
Also i am not really selling based on income, because i havn't actually tried to earn the maximum income via the site! its just a site i had running as a small project that suddenly got big!
The site runs really slow. REALLY slow. Maybe your one server is not enough to handle 60GB bandwidth daily? This seems like it really would eat a lot of resources. I think you would be better off making it image hosting and modifying your script a little. It's got a nice interface and the domain name is neat but it's not worth $1000 yet...
