Looking for a Website to Post Requests for Custom Craft Projects

I’m looking for a site that’s like Etsy, but instead of buying ready-made items, I would like to post a description of what it is I want and have others submit bids to create it. Ponoko used to be like that, but it seems to be all about 3D printing and laser cutting now.

There’s a section of Etsy where you can do that, actually:
