Kurt,
I've run a number of fund raising campaigns through Gofundme and have found the company to be very transparent and easy to communicate with. The transaction cost is around 8% of the total raised. The funds can be withdrawn at any time regardless of the final goal being met.
I don't know what your business model is, but if gofundme fits, I'd have no issues recommending the company.
Best wishes,
Rody
