CMS Website

Hi i require a CMS website for a Construction Machinery Hire website. the basic outline design has been attached to this project, all flash work will be done by us so please just accomodate for the flash in the design. Functionality of the website is as follows: Administrator must be able to log in and add and remove categories on the left hand side navigation, which may have sub categories so please accomodate for this. Once a type of machinery is chosen for example Telehandlers, then a page similar to the bottom part of the attached draft will be needed. Where each machine is listed across with a thumbnail, all these parameters should be able to be updated using CMS. Once user clicks on certain machine it opens up a further page with the title of machine, large picture with ability to add extra pictures as thumbnails below which come into the large photo area when selected and further information below of the machine below. Theme of the website should be similar to the Gunn JCB website graphically but functionality should be as described above. other pages required are as on draft design, of Gallery (wher admin can upload photos to display here as thumbnails becoming larger pictures) and a contact us page containing a contact us form and user must be able to add extra information here as and when required. Need something to show by friday. Logo will be provided, please match colour scheme.
