Integration Tyre Pressure monitoring systems into our Fitted Unit Portal

Who we are:\r\nWe are a B2B- SAAS Provider in Germany, founded in 1996, which provides a special solution for the Wheel and Tyre Market. \r\n\r\nOur Customer licenses a service for his Website/Webshop, where wheels and tyres can be found for a specific car, and can be mounted visually to the car. \r\nThis helps the endcustomer to see if he likes the look of the wheel on his own car, and also gives him the security, to be sure, that the wheel and tyre fit on his car (based on German TUEV Certificates).\r\n\r\nCheck the demo: \r\n[login to view URL]\r\n\r\nThe solution is based on PHP5, MYsql5, JavaScript, HTML, XML and does work with a template, which allows the customers to customize the look and layout to match his website. There are TAGS used as placeholders. All steps of the process are defined as layers in ONE HTML Template. \r\n\r\nThe DEMO Template: \r\n[login to view URL]\r\n\r\nWhat we are searching for: \r\nWe want to find a reliable experienced developer, which will work for us in the best case on-going on our application to add new features, fix bugs and add custom changes for our customers.\r\n\r\nKnowledge / Preconditions:\r\n\r\nMust-have:\r\no PHP 5 / Mysql5 / OOP\r\no HTML5/ JS / Jquery UI /XML\r\no Compatibility to all major browsers\r\no All changes are documented using SVN and our Issue tracking system REDMINE\r\no Projectlanguage: English, if possible German.\r\no For future projects: Responsive Design\r\n\r\nThis also depends on available budget and development costs.\r\n \r\nThe Current Project:\r\nThere is a new law in the EU, that all new sold cars, starting from November 2014, has to have an Tyre pressure monitoring system. So the task which is to be offered, is to add this information to the application: \r\n\r\n1. The Data is already stored in our database.\r\n2. SQL Statements already exist.\r\n\r\nWe need a fixed price offer for this project, including estimated count of development hours.\r\n \r\nWhat needs to be done:\r\n\r\n First Step:\r\n1. Add an Button and a Popup layer, in the same look as existing, to the DEMO Template\r\n2. Add TAGS to the Template and Template Engine, for Showing it in browser and to the existing form as values.\r\n3. ADD these TAGS to the INITIALIZATION mode, which fills the TAGS with the information of the first mounted.\r\n4. Change CSV Import and add \"articletype\" column to also import Sensors next to the existing wheels.\r\n5. Change shown prices by adding the prices of sensors.\r\n6. Add it to the RETURN Mode, which restores the last state of the application via session cookie, when returning from outside of the application.\r\n7. On each click on an wheel, a new request to the database is be done, and then the data is changed, also for this new feature in the popup layer, and the shoppingform.\r\n\r\nSecond Step:\r\n8. Add new fields to DEBUG Mode.
