Custom Actinic Single Product Page Layout

I would like an actinic single product page layout designing for my website. i have prepared a mock up of the design and have attached a snapshot of the area i would like constructing with our website.

The area where i have shown the main image and thumbnails at the top would ideally be an editable area where i can drop in different html depending on what i want there at the time.

The section below would be the item description on the left and product options and add to cart on the right as shown in the image. Headings and breadcrumbs as shown.
