Install modules and fix a few errors

This project is for fixing about 11 errors in OsCommerce and installing 4 contributions. Site must also be made w3c compliant but this is actually fixing wrong code. In this website are several modules installed already so be sure to have enough skills and communicate good. If you are good then more work will follow. Full payment of project will be released when an initial test purchase is done with no problems. Payment will be done by Escrow and only after project is 100% finished. NO exemptions as I had bad experiences before.
