Develop a PhoneGap app with Rails back-end

Develop a PhoneGapp app with Rails back-end Overview I want to develop a app similar to Uber for car wash but for just one company instead of many autonomous washers. Basically the user signs up, insert payment information and then call a washer based on his location (select services needed and precise location). We may need a Rails back-end to manage users, add/edit/remove services and prices, etc., as well as sending PUSH notifications to our team when a user requests a car wash. Itens on side Menu PROFILE Name Email Phone MY CARS Make Model Year Color Plate PAYMENT INFO Credit card info (number, valid thru, CVV) Biling ZIP code HISTORY List of the last washes LOG OUT Calling a washer flow: GPS gets current address and allow user to edit it User clicks on the "Call washer" button User fills the detailed form with service specifications and get total pricing Select services (checkbox) Select car from "My cars" list (select box) Reference and other instructions (e.g: car is on on park lot D11 on 1st floor). Select hour and minutes of when he needs the car ready User receives push notifications of each stage (wash started, wash finished, etc.). User gives a 0 to 5 star rating and leave a comment (optional). Any question feel free to ask! :) Suggestions are more than welcome and will be a significant differential that will make me choose you! ;) Thanks!
