Looking for a quality booth to paint your project?

AB Paint in Fremont rents their car-sized, filtered room for $100/day.  https://www.yelp.com/biz/auto-body-supply-fremont

They also sell paint / supplies for cars and can even make up rattle cans of the paint/color of your choice.

If that's to pricey, or you need multiple days, consider buildng your own paint booth with a PVC frame, box fan, and home furnace air filter. https://www.youtube.com/watch?v=Q3SOkRDZdt8&t=396s

Alternately, what I (Simon Weiss) ended up doing was getting in touch with a model maker and am going to use his booth in exchange for some wine. (contact through a friend, but some cold calls might work in the future).
