554410 PHP Script - Search no longer pulling up results.

I operate an online dating website that runs on a php script and utilizes the mysql database. We have had the same programmar / webmaster for the past 10 years, but he has since moved on to developing iphone APPS. Good for him, bad for us. We are currently having problems with the search function on the script. It stopped pulling up results for no apparent reason. We need this fixed ASAP. 1.) We need this issues resolved ASAP, and 2.) We're looking for an ongoing web programmar. This person must be extremely knowledgeable in php, mysql databases, coding, troubleshooting php scripts. The site has 19,000 members, and we need someone very experienced. If you think this is something you are interested in, please contact us immediately. Thank you.
