Need some help w/ features

[DesignerDani]

I am 98% sure I will be purchasing vBulletin, but there are a couple of features I am unsure about.

I will be running a website with
forum (vbulletin)
articles (vbadvanced dynamics)
blogs (deciding between vbulletin and vba dynamics)
vendor review (vbadvanced dynamics - I think)

Here is my sticky point. This forum is going to be mainly regular users, with paid vendors able to respond to questions posted.

I want those in the premium vendor usergroup to each have a page which describes their business. (business name, address, e-mail, few paragraphs on what they do, picture, logo) This info could be pulled from custom profile fields or somewhere else. I'm just not sure how to set this up and am wondering if there is an existing mod out there or something I can tweak to do what I want. I know I can set up custom profile fields, but I want this to only be shown to those in the vendor group - is that possible? Anyone have ideas or guidance on this?

I also want regular users to be able to post a custom date field in their profile which pulls off to a separate calendar. I've looked and don't see a hack for this, but I'm not always great at finding things. Also, I see I can set up other custom fields, how large of a text field can I add?

I'm looking for all possible solutions, existing mods, theories on mod I could create or a paid solution. I have some php programming experience but time is tight since I want to launch mid Aug and my baby is due mid July . Budget is also tight, but there is slight wiggle room.

Thanks to any who take the time to read this
