Yeah, you can do that. It will take some work. Just add in all the profile fields you’d like to use for the ‘business listing’ and then display those fields in a directory of sorts using custom template files. Or you could style up a member ‘blog’ theme that is formatted as a ‘listing’ with maybe some edit in place ajax functionality that’ll allow a member to enter their business info and restricts them from doing anything else. That way you could use sitewide queries to build a directory of these ‘listings’. I can’t say there’s a cut and paste sorta plugin to achieve this, but the best place to start would be here and here.
