Existing website, spring cleaning and makeover

My existing wordpress website has a lot of junk in it. I need it cleaned out. And the site needs a make over. I need a custom layout for my homepage and one new custom page for my video classes. I use a Thesis wordpress theme. This is a membership site. Must be an expert with wordpress and membership sites. I have an excellent track record with freelancer. Work needs to be done quickly and on time. May need some simple graphics. also have a simple line drawing of what I need on the homepage and custom page.
