App de bingo

I am looking for someone to create an app de bingo for both iOS and Android platforms. I have a rough idea of what I want the app to look like but I would really benefit from assistance in fleshing out my vision. The app should include a bingo game with the ability for in-app purchases. The perfect developer for this project will have experience developing for both iOS and Android, understand the need for attractive design, and be familiar with creating apps that support in-app purchases. If you think you're the right fit to create the perfect bingo app for me, please reach out and let me know!
