Android App, Iphone app upload to market

** Applicant must already have Google Android and Apple IOS accounts for uploads ** I already have an app created and need the zip file installed. It's imperative the application can be updated seamlessly from my end (we used [login to view URL]) and I'd also like to preview the app before it goes live. Again this is installation only, should be a quick project and we expect to pay a competitive rate due to this.
