It still sounds like it would be more promising to focus the business exclusively on providing a better mapping service. It's hard to build out all of the functionality for a marketplace (including dealing with very hard problems such as fraud), and then also to achieve the necessary network effects. It would be much simpler and more broadly commercializable to provide a better mapping/navigation service. As a potential investor, I would worry that you are trying to solve too many problems at once.
