According to the post, they paid Woodshed a retainer and were supposed to pay Woodshed a small percentage of the total if they hit their goal.

Court is the obvious way to handle it, but I see nothing wrong with going public to warn other people, or shame the company into paying up. The company is still apparently doing business. This goes a bit beyond not being able to pay your vendors, and depending on how exactly it went down, what Woodshed did could be outright illegal.
