"Enter Your Code" type website

This is to be a website where other website owners come to sign up for affiliation. after being approved they can get a code in which they can enter into their website. ( code must be traceable back to the website owner) when users on that website click the link the code provides they are takin to my website where a random 16 digit code appears. they click enter your code button next to the code and wait to see if they win one of any predetermined prizes. users ip must be logged and users can only do 1 code per 24 hours. if they win they fill a claim prize form and its sent to the admin panel for validation etc. if they lose there is to be a link back to the website they clicked through to get to us. MUST HAVE: Full admin: ..view approve edit affiliate websites info/sites ..change how much an affiliate earns based on how many code submissions are entered (i.e. 1000 users hit enter code to see if they win and for every 1000 they earn 5.00 or whatever set to in admin) ..afiliate payout request area (view affiliates who have requested payout, with accept and deny button) ..view codes and users ip of who entered them for that day ..add, edit prizes and how often they should be awarded ..winner panel where user prize claim information comes to Affiliate area: ..can view stats of how many code submission for 24 hour period, 7 day, and 30 day periods ..can view balance of how much they have earned and can request a payout ..get site code area where they get their unique code to be put into there site. ..afiliates website must be approved before they can receive the site code. Site Area: ..affiliates sign up area ....must send validation email to affiliates email to verify it ..enter the code page ..results page from entering code (winner - not winner) ..prize claim form (could be on winner results page) I think thats about it might think of something small later but for now thats it. post what you think you can do it in willing to pay more then 100 but trying to stay under 150. thanks alot
