I need a PHP application that will allow SMS sending. I have gateways already. I want the job to look more like [login to view URL] Here is case study: - admin can setup the gateway link - admin can setup the number free credits - users signs in with his details (username: mobile phone number and password) - user has a certain amount of free credits and can send free SMS - once the credits are zeroed the user can buy more credit - to buy credit the user will donate a certain amount 5$, 10$, 15$.... trough paypal, other payment mode should be available - credit is added manually by admin once the donation has been received. Credit should have an option to be added automatically IMPORTANT: My links for sending the SMS is built like this: [login to view URL];to=xxx&message=xxx I need the application to do the following: - user can enter to and message field and hit send Users should be able to personalize SMS - the application should send these details to the admin account and build the link [login to view URL];to=xxx&message=xxx - the link will automatically launch a pop-up in Admin browser and after 20 seconds the pop-up should be closed automatically - the pop-up is launched on the admin’ computer. - if the admin is not logged in the website will display a MAINTENANCE message. Simply put, the user is able to fill in part of the link that will launch on the admin computer as a pop-up. I will provide all pages in CSS and the functionality needs to be added. I will also give a flow chart with the web page structure and a flow chart with the functional description for a better understanding. The structure of the files: ADMIN - view/edit/ban users - add/remove credits (second password protection) - set SMS rate - login/sms history - website settings (View/edit gateway settings, define free credits, admin profile, ...) - view user (details, phone book, history) - send SMS - notifications User - view/edit profile (password and e-mail) - send SMS - add credits - manage phone book My Budget is $100
