Review my app - ContestFM: automated radio call-in contests

Your decision to build on top of Twilio makes a lot of sense.

There is only a limited amount of radio stations in this country. And most of them are owned by a handful of parent companies. This is a good and bad thing. Good because you can easily find the buyers. Bad because this could turn into a time consuming enterprise sales process. And this isn't something you sell on the web with a website.

Good luck! I'm thinking there could be tremendous data collection value in this business model if you add a few more features after you've successfully sold the MVP.
