Hello there
I'm working as cordova/phonegap and web application developer from last 1.5 year and have working experience in Php, AngularJs, Ionic framework, JQuery, JavaScript, Html5 and Css3.
As per your requirement I have my own admin panel totally ready to go. I just have to change some modules and add new one according to your requirements.
My admin panel also have web api so it would more easy to build mobile application from my admin panel. As many contents required in this project was already done by me and it's ready to go..
I have demo of my admin panel and also I have worked on so many hybrid mobile applications. I also can show it to you if needed.
Looking forward to work with you.
