Simple Roku app for my Radio Stream

I am a non profit. We are charity based. We do not have much of a budget. I really want to put my radio station on Roku. I own a Christian Radio Station. We broadcast via an HTTP stream using aac and mp3. I do not want anything fancy. I need a simple ROKU app with my logo and stream. I know this stuff is usually expensive. If there is a way to make an roku app cheap for my radio. I need someone willing to do it for under $100 or volunteer their time for a charity cause. We are a christian based station that helps with raising money for missions and good causes. I figured this would not hurt to ask if anyone is willing to do it cheap or volunteer.
