website clone

Hi, I'm looking to create a clone of this website: [login to view URL] Basically, its a freeware download site. The links (which are written as various sized words) towards the right hand side of the home page are the various categories, so those should be the categories, but in a proper navigation column. I need a site creating like that one, complete with ALL those freeware softwares uploaded into it, so a database will probably be required, I have mysql and php on my server. However, in addition I want to be able to charge an admin/donation fee, set by me, like $1 (but I should have the flexibility of being able to adjust that in the admin section, only 1 admin fee needs to be set which should apply site-wide to all products, so for example if I put it at $1.50, then it should be become $1.50 for all products). Payment gateway for admin fee must be paypal. Thanks
