There's no rush, but I'm not sure if commission-based shops are allowed in Pixel Projects. It's not in the rules, but I assume not? It would also require off-site payment, so there's another level of no-no there, too.
Assuming it's against the rules, please close my thread at some point in the new year. Merry Christmas!
