Mobile Application

I need a mobile web application and a wordpress backend. The mobile web app should be similar to the twitter concept; i.e on app refresh, a new content will be loaded from the backend, if available. Mobile web app will go highly independent from Mobile operating system. Supported browsers include; Internet Explorer Mobile , Safari, Android browser , BlackBerry Browser, Blazer, Dolphin Browser Firefox for mobile, Iris Browser, Kindle Basic Web, Myriad Browser, Nokia Browser, Opera Mobile Content to be accessed by the mobile web app is: text based data and a maximum of two images per content. Each content on the backend have unique dates. The mobile web app accesses each content by date. Thus; monday has its content, Tuesday has its content... etc. Access to each day's content by the client (mobile web app) is based on subscription. Users will pay using VISA, MASTERCARD and Interswitch Debit cards. Available subscription categories; (a.) Six months (b.) One year Users of the web app can advertise the entire mobile service by sharing a fixed text via; (i.) Twitter (ii.) Facebook (iii.) SMS. For SMS, app user will be billed from his airtime by the mobile operator in use on the phone. Mobile web app should be able to keep track of last visited page. Users of the web app should be able to save a given content of choice locally on the device but cannot transfer them out of the device. Kindly revert with the following; 1. Cost of project development and deployment 2. Project delivery time frame 3. Technology / Technologies to be used 4. Application support plan and price I look forward to hearing from you.
