I have decided to postpone the launch of my company until I know I have something worthy of making such an investment. I want to make sure people will be willing to pay and that I have some numbers to analyze before bootstrapping it any longer. Thanks for helping!
If you're asking about processing point-of-sale payments, have you considered using the smart phone tools available from Square, PayPal or QuickBooks? You don't need to have a formal business entity structure to use these. A sole proprietorship is a viable business model to conduct some sales and test payments.
To be honest, if your product targets the high value use case, people will pay whatever you charge. http://avc.com/2015/07/bootstrap-your-network-with-a-high-value-niche-use-case/
The other thing you could do is look at competitors and see what they charge, and how are they missing out.
