Wordpress catalogue/online quote site

I'm looking for an online catalogue/quotation site based on Wordpress with the following pages;

1. LANDING PAGE with 9 categories on it (as per design below) with the categories;
HD Cameras | HDV Cameras | DSLR Cameras
Lenses | Sound | Lighting
Grip & Tripods | Accessories | Consumables
This will also have a twitter feed on the front page

2. CATEGORY PAGE with 9 products/sub categories on it (with previous page, current page, next page navigation)

3. PRODUCT PAGE should be split with a large image to the left and a content section to the right which should be tabbed with details/what's included/technical/prices/accessories/more images.

Each of the products will have a daily hire rate and an insurance deposit value. The ‘prices’ tab needs a calendar selection to choose the start/end dates of the hire which automatically populates an equipment price, shows the insurance value and also has an ADD TO QUOTE button. The daily hire rate will be calculated on a multiplier table from the daily hire rate up to 4 weeks hire (after which a pop-up/error message will ask the user to contact us) based on the start and end dates selected.

4. QUOTE PAGE basically a shopping basket with no option to check out. The items added from the product pages will be added as items with a running total at the bottom.

5. NEWS page (to post news stories to)

6. GENERIC TEXT page (for contact us/about us etc)
