What can I do with my computers?

Hi

I have a computer training center .I have 3 computer sites with average 8 copmueter in each site. but now it isnt many customer for learning IT in my city.

I must use my computer and earn money in other ways.

I thought and changed one of my sites to a cofeenet for test , but it didnt yield as I expected.

now , what can I do with my computers for earning money? Is there another policy ? Is there another element that I can change my sites to that and get profit?

thanks a lot

You can just start a cyber cafe.

Or you can create sites like http://dmmteam.com , http://xhackerz.com, or make it a forum or you can sell things!
