Volusion expert for custom script

Hello, I need a custom script that I will be integrating in an existing Volusion cart website. Here is what it needs to do: - pull the contents from the cart and display them in a compact mode in every page of the website.? - you should be able to see the products' title, price, quantity, total and update the quantity from there as well as remove a product from there too.? - there should be a link to the existing cart page and a button to checkout (this will be done with the existing system - I just need the button there to send people to that area). Please make sure you only bid if you do have experience working with Volusion because I don't and will not be providing support or debugging your work. It has to be fully functional from start. Thanks, Andrea
