I am a Sr. Linux System Administrator for a very large hosting company and work in their server monitoring department. I work daily with customers who's sites are experiencing performance issues, and assist with optimization using a multitude of techniques. I have 7 years experience working with Apache and MySQL. Prior to this, I have utilized WordPress for 6 years in my personal endeavors. This is definitely something I can start immediately, and resolve very fast for you. Please let me know if you are interested.
