This might be an idiot answer, but have you checked your local makerspace? Or contacted someone at a university?

Last year a few of my classmates did an "Aggie Challenge" where they designed something for a private party in exchange for some mentorship and a resume bullet.

We usually do small projects for professors/companies that need help with something simple (like a CAD model/Design).

No, I haven't. I doubt reusable coffee filters are "cool" enough to attract that kind of attention. I need to somehow reach the people who are already making them, and they are almost certainly in China somewhere.
