I realize this is rather a late post to a most likely abandoned topic, but there are sites out there that freelance PHP (and a plethora of other languages/services) can be hired for a project.
There is also a couple sites I've seen where someone can sell their program they've already made. Which would include your licensing idea.
I'm not quite sure of the URL's to the sites, and I've never actually used either type before, but I'm sure with a few moments of googling / scanning you could find them. They're pretty much everywhere. Some big, some not so big. Almost all of them have secure transactions and some type of garuntee for payment and delivery of product.
And well, if I'm causing havoc or un wanted attention to this topic I apologize, just thought I'd let it be (somewhat)common knowledge.
