My company, From Concept to Completion, handles a variety of projects. We do boutique ad agency work, demonstratives for litigation, photo shoots...and in recent times, social network consulting. This typically consists of addressing the typical solutions (Facebook and Twitter) and finding industry specific solutions (music = MySpace, art = ArtSlant.com, etc.).
I'm interested in hearing about your industry specific solutions. Got any favorites? I'd love to check them out. Please add your ideas in the comments.
