A couple additions to my PHP website (SIMPLE)

Hello, I need a freelancer who is proficient in PHP and in the english language. 1. On my homepage my login does not work. I need this fixed. 2. Flash on my site loads every time you click a page, i only want it to load once per visit. 3. I want 2 videos merged, and placed on my homepage right below my picture. (They are already uploaded to my website) 4. I would like a web-page pulled up under one of my tabs on the public section, and one in the private section. 5. The K-Vest web page does not look identical in any browser but firefox. Using safari the video does not take up the whole page. I would like this fixed. And that is it, i assume anyone who knows how to do this stuff well could do this in 1-2 hours. Please tell me why you are qualified for this project.
