Things that I can provide:
1. A starter app that involve database (Firebase).
2. Simple login and social logins (Facebook and Google) with Firebase.
3. Master - details application.
4. Some common ionic plugins such as geolocation, camera, contacts etc.
A prototype is good for validating a business model. It comes with minimal price and time before greater investment.
*Latest updates: I can do in Ionic 2 and Firebase 3
* Note that the minimum charge is $100 due to excessive requests. However, if you think your request costs lower than that, feel free to contact me too.
* Please take note I might reply late over weekends.
