Create/Customise BigCommerce Template from existing site

Looking for someone with BigCommerce template experience to create a BigCommerce template from an existing non-BigCommerce website, so that the BigCommerce site will end up looking similar. Template needs to have the look and feel of the graphical elements of the the following existing site: [login to view URL] The BigCommerce template needs to incorporate the existing logo and existing colour palette, and buttons used for actions, where possible. There is NO need to do any of the products, banners, Javascripts, or any BigCommerce SEO/cart optimisations, as all of that will all be already part of an existing BigCommerce site. We just want a new template that can be applied to the BigCommerce site to give it the appearance of the existing site.
