On-line PHP Booking Form

I require an on line booking method for our technical staff to be remotely booked for particular work in the field. The idea being similar to an on line hotel booking, whereby the respective technicians specializing in, say, the underground radio communication field, are available until booked by either our company or other companies which use our services. We would firstly need the particular person to register with their details, and the respective approval from the company they are employed with. Once we have received this registration, we would issue a certificate/thumbprint/password which would allow the individual to book from a remote location via the internet. In our office we would like a terminal which constantly displays this information in order that our technicians can schedule themselves and prepare for the work ahead. This would really only be a screen. NEW INFO ADDED 18 MAY 2008 1. We would also require to be able to see each technicians availability for 4 weeks in advance. 2. The system must also be able to have more than one technician booked out for the same job. PS. I will create the website (look & feel) in basic html, in which the Booking application must run. ## Deliverables The web based application will be running on a Linux/Apache server with Php version 4.3.11 (can be upgraded to ver 5.2), MySQL version 5.0.32. If there is any other info required, please let me know.
