upates to magento website

I need to make web performance optimizations for my website, includes: - Add Expires headers to static contents. - Remove render-blocking JavaScript ( i think we can do that by adding js in the bottom of the page + move 3 inline JS code in js file). - Use cookie-free domains ( create new sub-domain for static files ). I am asp.net developer, so i know what i am doing.. If you don't have prev experience in magneto, please don't bid if you can't accomplish this work within one hour, please don't bid
