Blog Modification

I need a header image installed on a blog. The site is located here [login to view URL] What I need is to change the overall look and feel of the blog to match [login to view URL] Just the color scheme. I have the header image but need to have the template edited. ## Deliverables I also need for the visitor to always land on the home page even if other posts have been entered into the blog. What I mean is if you type the url into the browser you will always be taken to the home page.
