537841 Server and design optimization (speed and revenues) 2

Currently I have a website with around 5000 unique visits per day. I used to have 20,000 before migrating it to Wordpress. And a vital issue to the reduction of the visits I think it has been the loading speed. I need someone capable of optimizing my server, optimizing or doing a new design, and optimizing the adsense revenue. I am currently only doing $3 per day with 5000 visits, that's absurd considering what I did in the past was 10 times that. Bounce ratio is around 75%. Site will only shared via private. Only reliable people needed as I will have to grant you access to my server. It's a Linux server. Will pay by escrow.
