I am trying to setup my zen store. I will be selling Quality Pre-Owned Mercedes parts. onzes twozes and so the bulk of my dreaded work is listing parts. I need an efficient method to add parts to my store. As in click type description, click click and it's done.

There are a few things I would like to change on the product entry interface, l would like to add/change or create a new product.php to do the following:

drop down box for VIN - I enter VIN once and it gets added to a drop down box for future listing of parts
VIN puts the product in the proper category (make & model), I select subcategories - engine, chassis, interior etc
automatically insert quantity as "1" unless I override
Entry box for MB P/N 0123456789
auto populate meta tags with mb p/n model etc

wish list:
be able to select multiple images for upload
automatically move images to a "sold" folder after sale

I'm sure there are a few more changes desired, but the above are highest priority.
Any help is appreciated, and compensation can be offered.
