WHMCS Cart / Order Form Template

We are a small Web Hosting Company. We use WHMCS for our client management, billing & support. We already have a full frontend website (we will supply the URL when needed), however we require a redesign / rework of the WHMCS shopping cart. The new cart should blend into the rest of the site (colors etc). We are not looking for hours and hours of work, only a redesign of one of the cart/order/checkout templates. We are happy to take advice on which order form template to start from. We do have a number of example sites which use redesigned carts which we like. We can forward the URLs as and when required to show what we are looking for. The designer should already have created other works and modules/templates for WHMCS. We require the designer to be able to communicate effectively in English. If you already have created a cart/order form for WHMCS we may be interested in purchasing this.
