Hi,
We have expierence in building application using PhoneGap framework. However we prefer write native application for both platforms. PhoneGap (and simillar) declare "writing one codebase" but actually such approach has lot of disadvantages, among them:
1. Extremelly poor performance (your application has lot of animations, we will spend lot of time to making them smothly in WebView)
2. Not all phone features available for application
3. Html 5 frameworks have limitations
You may google for more inforamation ("PhoneGap vs Native")
We can develop
frontend interface data services - $2000
Android native app - $2000
iOS native app - $2000
Windows Phone app - $2000
Please consider the possibility to have our team as mobile development partner or just to utilize individual developers from our office in Kyiv, Ukraine. We will organize excellent working environment, taking into consideration your preferences, with daily communication, progress overseeing, ideas contribution and further support service.
