Alright!!! Yesterday I have finally managed to complete the "ideal" back-end functionality for my app.
I want to say a huge thanks to the StackOverflow community for all the help and advice and especially Daniel Roseman. Daniel if you are seeing this, thank you very much!
The only thing I have left to do before I launch the app is the homepage design and the logo. I anticipate this will take up to a week and hopefully, I will launch a free version of my app into the world.
I plan for it to stay free until I build a second version of MVP and learn how to integrate Stripe into the signup process.
