Phonegap Developer Needed

An expert phone-gap developer need to take over my existing app, Configure web back-end and setup properly, make very small color changes through its CSS, replacing logo and a splash image and then generate its Android apk and iOS iap file. You must have a web server for my web back-end. Project includes listing the app both on apple and google play store. ONLY after successful iap and apk file generation, MILESTONE will be created and released.
