Cross Platform Compatibility

Dear Bidders, I have a user login system similar to the one that is on the URL; [login to view URL] This is programmed according to PHP5, Linux OS and Apache Webserver. I need some one who can make this User Login System to work in Windows Server 2003 running IIS7, MySQL 5, PHP5 via FastCGI environment. Please note the script is running fine at Linux, Apache, PHP, MySQL. I cannot provide access to the Windows Server and hence instructions or modified files can only be uploaded via me. I need someone with similar experience and can guarantee positive results ASAP! I will provide the files once the bidder is selected, and work closely in order to fix this situation. Thanks Sam
