wordpress quote website

My client needs a wordpress based website. It will use an off the shelf theme. The theme and wordpress will be installed by myself. The only thing we need from you is the catelogue feature which will be a simple drop down to chose item = select size = price. I have seen some wordpress plug in's that do this just need it configuring. here is an example of what I need: [login to view URL] You will see 1 product has various variations, like sizing my client may also need: select finish> select handles> select colour of furniture = a specific price. Once they are happy they have selected the furniture they require they then accept quote> which basically e-mails their details to my client, with what they need and he will contact them to arrange delivery / payment. I only need the plug in customising and 10 products loading, I will load rest and wordpress / theme etc will have already been install thanks.
