OpenCart extension developer wanted

Looking for programmer to write an opencart extension to integrate Minify in opencart. Minify site: [login to view URL] Someone else already made such a mod: [login to view URL]://[login to view URL] I bought and have this available for you as reference. I would need an extension that does exactly the same as the extension mentioned above. How much would it cost to let you to 'clone' this extension where you rewrite it (so coded from scratch, don't use the code from the extension)? So don't violate the intellectual property rights! Need full rights to the code you programmed and want to be sure you won't (re)sell the code.
