Have an existing PHP/MYSQL hotel reservations script that we wrote about 6 years ago and have patched and corrected as we went. We would like to update security standands and protect against SQL injection. We are also looking to add new features and change some of how the current system works. current system in demo here: http://networkreservation.com/oldres/ NOTE THIS SYSTEM EXISTS AND IS WORKING: You are not bidding on a request to write from the beginning.
