Troubleshoot wordpress database and setup multisite install

Avg Bid (USD)
Project Budget (USD)
$30 - $250

Project Description:
I have 4 wordpress installs, 2 of which are hosted on mediatemple and are running extremely slowly. My suspicion is there might be a database issue or database connection issue of some kind causing the speed slowdown.

Two other sites (more recently created) are hosted on Wp-engine.

I need someone to troubleshoot and solve problems for the first two sites then I would like to combine all 4 into a multisite arrangement.

Skills required:
Database Administration, SQL, Wordpress
