Server admin needed to optimize server performance

Hello, I'm looking for a CHEAP and EXPERIENCED server admin to add some configurations to my server and optimize it's speed. Currently I'm running a video script from [login to view URL] and after restarting the apache and getting some users to the website all of the server becomes very slow and not usable. You need to know what might be the reason behind it and search online for how to optimize the server for this specific script. This should be a simple job for an experienced system admin. NO DOWNPAYMENTS (MILESTONES) NO BIDS HIGHER THAN 50$ THE CHEAPEST HAS A HUGE ADVANTAGE
