Customize A Wordpress Theme

I am planning to buy this theme and I want the following changes in it: [login to view URL] 1. Substitute the logo. 2. I have created an image for a navigation menu. That needs to be converted to CSS. 3. The over all color of the theme needs to be replaced from orange to blue. 4. The "posted by..." line on the homepage under every post needs to go away. 5. A comment icon (i will provide) needs to be added to every post on the homepage. It also needs to show the number of comments just like [login to view URL] 6. For bullet lists, there is a certain icon that I want to use. I will provide that icon. 7. The main font of the posts needs to be changed. 8. I need to have an image incorporated for the H2 tag, just like in [login to view URL],com. I will provide the image.
