Developer/Designer - Social/Business Networking Site

We have a very nice collection of domains in a certain niche and have only started a small social and business networking site that is getting traffic. We need to move away from the current software (no worry about moving profiles) and are interested in drupal given some of the fantastic results I've seen for such sites.

I'm glad to provide more including a list akin to an RFP but don't want to put it out in public here, as you can understand. Ideally this site is in a niche community and requires the ability to have profiles that can be used for both dating and business, the user choosing how much or how little information to share. There should also be a choice for what the user is looking for, e.g. dating or business networking, etc. If there are suggestions about using a separate integration of a dating script, e.g. osdate, then we are open to the possibility of using external scripts together. This might be the case since I'm not sure whether it's an easy task to add about 25 categories to a user profile and a good mechanism to search them all.

Essentially we are not happy with phpfox for the obvious reasons. It does many things we want but none of it well or organized. Handshakes is also not an acceptable script for performance reasons amongst others. In listing some of the items we need to accomplish, they are as follows:

1) Dating/social profile and functionality
2) Business profile and functionality
-- These two need decent profile collection information and search functionality, e.g. by gender, location, profile details that you'd regularly see

3) Picture (and hopefully a video) gallery with ability to add comments and categories (e.g. weddings, events, etc.)
4) Events/calendar listing
5) Classifieds
6) Groups (optional since forums may serve this purpose)
7) Forums - we have vbulletin licenses and if there is easy integration this solves another issue. Willing to hear of other solutions that are acceptable although vb has worked well.
8) User blogging
9) Magazine/publishing area for a weekly edition
10) Reviews/Ratings for a variety of items, e.g. movies
11) Commerce component (not so important, suggestion is ok for now)
12) Newsletter component or ability to export into an mailer, e.g. Octeth
13) A Q&A area (like on http://www.mothersclick.com/)

That's a pretty good basic list. I have example sites that I'd be willing to provide that show a good idea as to functionality I'm looking for.
