Hi Thomas,
If you guys are still looking for the right Spine animator for your project, I believe my particular skill set and experience would be quite suitable, as I can confidently check off every single item on your "what we're looking for" list. Although not a programmer by trade myself, I've helped more than a few programmers with no familiarity with Spine get up and running in Unity, which sounds like it aligns with your needs.
For a bit more about me (and to see my reel and other content), just check out the thread I recently posted.
I know your listing is from a couple of weeks ago, so if you've already found somebody for this particular bit of work, I hope you will keep me in mind for any future Spine-centric needs.
Cheers,
Matt
