السلام عليكم ورحمه الله وبركاته,
I hope you are doing well, I have read all of your requirements and happy to tell you that it would be my pleasure to work for you for this great app.
I have done similar projects in the past, But I never had the oppertunity to work on a Quran app.
Let me know if you want to talk further, I would be happy to assist you if you have any questions.
Regards.
