Hello sir
I have interested your project and so felt the desire to develop it as the android export.
I have developed many android apps using the android studio and eclipse for 5 years and so have the enough experience about it.
As a typical project, I have developed the taxi app (Hello cab), Fantasy Alerts, Yostapp, Compare Image, drawing for toddler and so on.
Especially, I understood about your app entirely and so I think your app is very easy to develop it for me.
Of course, it is not so important and more importantly, to develop it wonderfully so that you're satisfy about it.
Firstly, I'd like to see your mock-up about this project.
I think the design is very important because it is the first interface with user in the app.
Therefore I need your mock-up of this app and If you accept my proposal, I'll accomplish it quickly and quality with lower price so that you're satisfy about it.
Of course, the choice depends on your mind and I respect your opinion.
Again, I have the full experience to develop the android app and so can accomplish it better than another freelancer.
Please believe about this point.
I value my credit and always will be kept the promise with you.
Finally, I'd like to work for your app with you together and I'll do my best for you.
Thanks for looking my proposal.
