Customize a shopping cart

I am thinking more along the lines of $30 on this. A good job could result in a bonus and a substantial amount of more work in the future. This is a test project to see if I can find a worker for a long term working relationship. I have already installed Magento shopping cart onto my website. I am now looking for somebody to customize this to match the rest of my site. I will also need the link to the shopping section of my website updated on my navigational bar to reflect the new cart address. It is php so only one file will need to be updated. I will also need the php file updated that controls the bottom four boxes on anthonychurch dot com (type the url into a browser) so that the last box is removed ("anthony's blog") and the other three are made to be wider, covering the same area that the four that are currently there now cover.
