Dear Marwan,
I got an idea of the application you want to develop. I will provide you details assistance in all process from designing and developing a user-friendly application to marketing it over web. I have mentioned below details about milestones (phases).
1. Wireframing: I will provide you overall screens of application with working prototype of your application. It will take 2 days for me.
2. Application Development: After you sign-off wireframes, I will develop first beta testing application in about 4 days and give it to you to test it.
3. Final Version: After you test the beta application I will refactor changes, if any, and then upload it over Google Play Store and Amazon App Store. (refactor change duration depends on changes)
4. After Launch Marketing: I will help you with digital marketing tips and tricks and also with PSO (Play Store Optimization) for greater reviews, ratings and downloads.
I will also provide you some proper suggestions to earn money from this application without affecting users.
Please award me the project, so we can kick start the above process. Looking forward on this interesting project.
Regards,
Omkar Todkar
