Looking for PHP Pro URGENT !!!!

Looking for a PHP Pro who will based on a already created webdesign build the backend. The site is basicly selling selling subdomains of some nice domains. On the frontpage there should be a box where users can check the avaibility of subdomains (from diffrent domains) and be able to register/buy them also in bulk. There will be 3 buy options (prices) which depends on amount. After buying subdomains he should be able to login into memberpage and see date of creation and expiring date and be able to change the dns of the subdomain or to point the subdomain to the IP of his hosting. a small adminpage where i can check amount of subdomains sold,see a list of all bought subdomains,add or delete manually a subdomain to a customer and change prices per subdomain and be able to add new domains. Site needs to look very professional and work must be done REALLY FAST
