Back end including database for small booking system

I have completed the design for this very simple booking system. I require the back end database and other programing functionality to be completed. I have added a zip file which includes the site. Please extract it and click on the file **[login to view URL]** as this has page specific notes and the structure of the site on the left of the page (to view page specific note, click on 'Page Notes' on the top left). Most of the buttons are self explanatory, for the buttons that are not I have added notes, these can be seen by clicking on the top right of the button. Please have a detailed look and ensure you understand the functionality and exactly what I am looking for. Please reply with the following: (Bids that do not answer these questions will not be considered) 1. Programing languages used - including which database 2. Time needed I think that's it, thanks for looking and I will look forward to receiving your bids. Cheers, Brian
