Improve Sendroid SMS app

Sendroid is an web app that permits to resell and send bulk SMS using http API : [login to view URL] That app requires following changes to fit my needs: 1. Build a new billing module : a. Add LCR logic : Currently Sendroid accepts to import a rate table and then add a fixed margin to all routes. It is required to add multiple rate lists from assorted SMS providers and then system checks and finds lowest cost route and selects it. b. Use real money not credits to charge customers c. Build a real time report showing consumption of balance. 2. One of my providers uses this API: [login to view URL] and it and it is necessary to find a way to make that provider work along with Sendroid 3. Solve some Sendroid bugs: a. Sendroid provides a URL to post SMS messages using my customers credentials. Those http API URLs work fine for actions such as show current balance but not to send SMS messages. b. Change login screen looking to white and add custom logo c. SMS custom buffer was created so Sendroid now is able to process over 100K SMS in a very realiable manner. Problem was that developer created a webreport that is not integrated with looking and menus of Sendroid app and therefore is required to show it as a part of app, not only for Admin user , but for Reller user and also Customer. d. Fix a bug that shows a message when a new Gateways is being added to Sendroid e. Identify basic security "holes" on Sendroid and fix them DO NOT BID IF YOU ARE NOT 100% READY TO MAKE THIS PROJECT COME TRUE DO NOT BID IF YOU HAVE NOT FULL TIME TO WORK ON THIS PROJECT
