Ask HN: Experience contracting designers for a brief UX review?

I have a number of simple projects that I'm happy to do the UI development for but feel their appearance or UX could use some critique from a more skillful designer. I'm not looking to hire someone to do designs for these small personal projects, but am wanting to pay for a 30-60 minute consultation to get general feedback and suggestions for improvement.

Any recommendations for finding folks interested in this sort of one-off design review work?
