I need a woocommerce and contact form on a website - repost

Hi I have a client who wants to add a contact for to his website [login to view URL] The two boxes Professional Installation service and Free Delivery Available need to be replaced and styled to the contact form. Second part of the project is If you have a look at a product such as [login to view URL] I need price variations for Roll Lengths, so if it was 2m width and 3 metres long that would cost £33 as it would be 3x11, then 2m width by 4 metre length would be £44, 2m x 5m £55 etc It needs to be done asap as the site is LIVE and bringing in traffic Thanks Paul
