Convert website - asp/flash to php - Mobile site

Please read fully and understand before placing any bids as if you fail this step you are not suitable for this project. The Project. My client currently has a bespoke website/system which is aimed at property rentals. This displays availability, bookings, sends out emails, reports and also manages all the bits in between. Data is pulled from the main database converted to flash and displayed on clients website along with a owners area. A number of templates are in place to allow owners to build websites these again need to be updated. The Issue. Due to the system being written in .asp and flash many parts are not displayed on mobile devices. Options. Re-code the .asp to .php and flash making adding new features easy. Develop a mobile site, when a mobile browser is detected it points them to the mobile version. Security. This is very important as data is being pulled from a central database only that users properties and data should be allowed to be accessed. This part the successful applicant should come up with a solution for this. Please ask any questions and also please request the link to the help documents so you can fully read and understand the system before placing a bid.
