I think a marketplace connecting hardware gig workers and hardware solopreneurs is a great way to solve this problem.
Here's the overview,
- The solopreneur supplies the design, build, QC requirements, buyers list to the marketplace.
- The marketplace finds the suitable gig worker for each country in the buyer list, Calculates the BOM plus build cost including the gig worker and marketplace fee. The marketplace sources the materials locally to the gig worker and acts as an escrow for their fee.
- Gig worker builds and ship the product locally using the logistics services of the marketplace. The market place releases gig worker fee.
