Hi there,
I have looked at your proposal and am confident I can offer you a professional product in a few days. If you have any additional details about how you would like it to look or the structure please contact me and I can begin work on it immediately.
I have worked on several infinite runner games (you can see in my portfolio that I have published one independently to the Google Play Store) and will happily help you bring this idea to life.
Thanks,
Niru
