Dear Sir
I require previous discussion about the project to be confident that I can deliver exactly what the client wishes. Honesty, responsibility and professionalism are essential for me because the client has to be happy with the service.
It is important to mention that I develop apps under a platform which differs from programming development.
After publishing the app, my company requires a contract and a monthly payment for hosting on both stores and in the platform.
The client has also to be aware that I will give him the control panel access of the app for content management, but support is not included in this price. If the client wishes the service from us, there will be a monthly fee for it.
The app built and Google Play store publishing are quick, but App store takes from 2-3 weeks.
best regards
