I've worked with a couple friends just for a few hours or something. I know they'll work hard but it's hard working with me. Been working by myself so long I rarely ask for any help while having somebody there to help. I would not hire a friend for a long gig though, a week or month whatever, just tends to mess up the relationship especially if the schmidt hits the fan and you have to get into their arse for some reason over a job related issue.
