Hello,
Would you please provide me any Project Requirement or Wireframe of your project so that I can get your idea fully and can be revised my price finally?
For your concern, we have developed 250+ apps for Android, iOS, BB, Windows Phone and PhoneGap so far. So I'm very much confident enough to develop this app.
I'd like to chat with you for discussing the workscopes of this project asap. Please let me know your convenient time.
Looking forward to hearing you soon.
Thanks.
