I only use people on a "per job" basis, and most of my talent comes from two pools... the tech college/uni students and new immigrants... there is a shitload of reasonably priced talent in those groups if you go in with the expectation that none of them are going to stick around very long... for me it works out well, as I get a large pool of talent to call on, and for them they make some extra money... for our web design side of the business (isnt it a shocker I dont exclusively do adult stuff for a living?
) I always give them a time limit on when a job needs to be completed, and a third of the way through that if they dont have a decently acceptable amout of work completed, they lose the job.. that gives me some cushion in case the client needs any rework done... or I need to pass on the work to someone else... that way they all know I have other people who can pick up the slack so if they want to get paid or if they want more work they have to get their shit together...
