I guess topcoder could be one idea for haiku.
http://www.topcoder.com/
At least it could be worth an experiment, because as I understood topcoder has many users who are working for not that much. (Also people from china etc…)
If you look at that page you see “contests” that are related to projects… and the winner gets 50 dollar or 100 dollar. Etc…
I think it would be worth an experiment, perhaps like this we get also new contributors…
