Create a Shopping Cart System For Mambo ( [url removed, login to view] ) or port over ZenCart ( [url removed, login to view] ), OsCommerce ( [url removed, login to view] ), or both with the attached specifications.
I have a Port of OsC that I created, and is mostly completed, but there are serious problems with undefines, and things not complete. You could use that as a base. We think it would be easier to port it, but if not we would require complete ownership to the code. If ported, we will require ownership until a public release.
