Hi Randy, I hope you're keeping well, it must be tough working without pay!
This sounds like a very interesting project, and I would like to help you with it. I usually design for my local jewellers, thus I haven't worked via Freelancer in a long time. I've currently started my own venture, so I'll only be able to help you 2~3 hours a day.
What is the purpose of this idea of yours? Is it for self satisfaction or do you want to mass produce and sell? If you want to make money of this idea, have you thought of the potential costs and clients? Although it won't affect me, I don't want you to spend your hard earned money on a dead-end venture.
Contact me if you want to chat about your project, no obligations.
KInd Regards and Good Luck
Johan Nel
