Newbie... kick me if this is the wrong place to ask about elements I need...

I'm versed in building old-style non-interactive html websites using just css files. I've basically built such a site with the LOOK I want, but I need the interactivity of Drupal so new Participant vendors can each have yearly-paid access to a pre-formatted set-sized division (think of a directory introducing a growing number of Participant vendors displaying their company splash as you scroll down the page).


I need each Participant vendor to have right of access only to his/her own (new Participant Drupal-assigned) pre-formatted "division" so they can submit, say, a 300x300 jpg on the left and some max amount of intro text and / or logo on the right, plus a button linking to their own entire page on the same website which they would also have tools to set up with more freedom as they wish, preferably drag and drop for their jpgs and auto-formatting textboxes easy for non-techies.


So each vendor has his own (what I always called) css predefined table to fill in within tight parameters on a front page to keep a fairly uniform site appearance. Each new table or division created gets added to the existing scrolling "list" of divisions, automatically inserted alphabetically by the Participant vendor's company name.


This is for a website introducing independent perfumers' fragrance lines, so I need a deep-toned zen-like high-fashion look, not bloggish.
I've designed some beautiful page-width horizontal jpg division separators I'd like to use as well as a Flash-based page header with a perfume bottle spewing beautiful colorful "fumes."


Are there module sets someone can recommend to me?

Thanks a million in advance!
