Change template look, change functions,

I need someone who has the ability to modify a ebay like script to make it like seo clerks. ***** sample modifications needed***** change the auctions to buy only change the wants so freelancers can bid on jobs and add what they can do for the user, the user then can pick who they want to do the job. I need all the same fuctions seo clerks has but in the format like ebay. I need all file names changed and a script licensing system that can't be modified or hacked. The admin will have to be modified also. Template design will need to be changed also. before job is awarded we will have a full understanding on all fuctions that are needed to complete the job.
