129754 motorcycle/tractor/atv display

I need a cms/product manager built specifically to display large ticket units such as motorcycles, tractors, atv's, etc. I want something similar to [login to view URL], but simpler and not geared specifically to automobiles. I expect the front-end display to be template wrapable (header/footer) and all unit display to be css as much as possible. W3 compliance is desirable. Requirements: 1. 7 specified content type fields (price, engine, drivetrain, transmission, make, model, year). Make and model will be dropdowns with data entry capability (if a make or model doesn't exist in the database a user can enter it without leaving the screen...think WordPress categories on a posting page). Year, make, model should all be used in the front-end display templates meta tags for title. 2. WYSIWYG field for additional details on the unit. 3. the ability to add fields and labels dynamically. At least a dozen additional fields are necessary. If a field isn't used, it should not display on the front-end (this is true of the pre-established 7 as well). 4. at least 4 pages of WYSIWYG managed content to be used for home, about us, specials, contact us. The possibility of one-click addition of pages would be great. Page editing should include title, description, and keyword fields to be used page meta tags. 5. Minimum 5 image per-listing upload capability with lightbox display on the unit display template. 6. The ability to delete listings with "Are you sure?" verification. 7. Customer contact form - the "contact us" page should have a customer contact form requesting name/phone/email/comments. It can also be used as the "request info on this unit" form if we pass unit information to the form from unit display pages. 8. Financing application form – method of submission to be determined, should have name of vehicle passed to it via query string. Admin - The site will be managed by non-technical personnel within a dealership. As such, it is important that the backend be as easy to navigate and understand as possible. All steps should be taken to consider the secretary, parts counter guy, or mechanic that might end up managing the site. Web apps are not going to be the core competency of the content managers. The ability to have multiple admins is preferable. I am NOT against a WordPress plugin/widget to serve this purpose, but the winning developer must be prepared to create a bridge between WP and a yet to be determined shopping cart for the sale of parts and accessories for these dealerships.
