Job Description

I need a CentOS expert that is very good in PHP to check out my server. It appears that I was hacked and my php processes were taking 90% of the processor yesterday.

I reformatted the server and have resotred all backups. when I load the website that was having the problem I get the same thing. The other websites were not affected. I need someone to find the hack and remove it. they put in place security measures that will prevent it from happening again.
