Ok,
First thing I noticed is that you're using only nbanners with a bit of, almost invisible, text underneath them. Try to write some good sales text and make that the surfer sees the text. You also want to use more "call to action" text like "Click here to blabla ... at Sponsorsite.com".
Second, your pictures are way too big, try keeping them under 80kb
Third, you're allowed 3 outgoing links per page, try to use them all 3. On your main page you're only using one.
Oh yeah and welcome to the board
