Demo mapping app.

A little background I own a GIS consulting business and my clients are asking for iphone integration for their trail systems. I do need one demo so free to low cost is important. Since it is using an sdk there shouldn't be too much work involved. I have a map ready to go for a client demo. Use mapbox open sdk to create a complete offline mapping solution for my clients. The app will be tailored to each individual company which means lots of return business. ( [login to view URL]) My idea is to have a main splash screen on the app where users enter their email one time. This gives us access to their emails. You can now sell their email addresses as advertising. My idea is to get one local business to sponsor the app for "x amount" per year. Everyone that now logs into the app their email is sent out in a batch to the sponsoring business to use as advertising. I could even have a section on the app dedicated for the business and their weekly sales ect. Email me with any other questions. I would prefer to work with someone readily available to make 50-100 tailored apps in the coming months. Please have a phone number or webex. Some other form of communication outside of email.
