I agree with Towelie you should showcase your work and then people can have the option to link elsewhere to buy things.

Where in the world did you come up with a definition for contribution that didn't involve something around the term "give" or "free"? I'm sticking with the definition that I've always heard of so far and saying this is for giving to the community, I like the showcase idea for people who want to sell things.
