Here's what I'm thinking. As we have min. production setup costs to print a new card design:
1. Project is interested, checks with audience
2. Project sends graphics (one or two designs, ...)
3. We host a "commitment" page per project, where people can see the cards, and pre-order. The pre-order already includes the shipping costs, etc. - so the entire order is pre paid.
4. Within a given timeframe (month?) we either hit the minimum sales (100 customers) or we refund everyone's pre order costs
Something like this?
XRPL project branded Xaman Tangem cards?
