It sounds to me as though you just need a set of people who volunteer to help others, without them having an official flag or custom group. You could show who is part of this by a badge on their userpage.

A custom group wouldn't have a badge like admins do anyway, so it wouldn't be shown on their profiles. Although, now I think about it, it might be possible to add a badge using the site CSS/JS

That's advanced stuff though, so a notice or icon on their userpages would be simpler
