It seems to me that the purpose of the fund is to:
Generate income + validate donations → so you can refund if needed
But by opening up your services to people outside the fund, now the purpose seems only to generate income. In which case, why not get the services funded by a private funder or EA funds?
This would be way simpler, as your job would just be to validate donations and transfer money. Which seems like—if nothing else—a good 80⁄20 to start out with before trying anything else.
This is great idea!
