Script Cleanup (Uses too much CPU!)

I have a script based on MySQL, PHP and HTML that needs tweaking slightly. Basically, it is using too much CPU and MySQL as it is currently designed. I want someone who can easily understand MySQL/PHP to have a look at the script and edit it so that it uses much less CPU/MySQL. The script is basically a traffic exchange script. It works out if a hit is unique and then credits accordingly. Also, two advertisers sites are shown. What you really need to do is get rid of some of the queries, and simplify the whole process. I am working to a small budget, but I believe that this should be easy for someone with the right experience. ## Deliverables 1) New Improved Script 2) CPU / MySQL usage must be down to "green status" on my server 3) Script must still function 4) Must all be copyright of myself 5) Must be done quickly and efficiently!! Experience probably required... ## Platform PHP MySQL HTML
