Clean up my code

My original coder is out of town and I need a PHP expert to clean up my script, these are PHP files that are developed around the the link sizzler, 97 tags, wordsitebuilder type script,but, the script has a unique twist. Needless to say, the twist isn't working like I want it too and I need a coder to fix it. I need a PHP expert who can also guarantee a zero failure payment process when a vistor buys a word, to include 2checkout and paypal. Also I need someone to do something about the appearance of the pages that each visitor/customer sees. I will send a copy of the script and explain the flaws to the winning bidder. I need this finished in a week. Unless you are a master of PHP, CSS and can ensure a flawless payment process (I will use my paypal sandbox account to test), please do not bid ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
