Thanks for the feedback. I'm about to post another couple CL ads (gulp) and will take some of the advice to heart. I'm going to post info that we do drug screen, do a background check, and check references. I guess the idea there as much as anything is to determine if people are willing to go through that, and if they are they probably have little/nothing to hide, or are mentally in the right place.
@Devin, I'm not trying to be rude/denigrate, but there's gotta be a middle ground. Sure, there's a learning curve to carpentry, but after my 2 years of working on these things, I can hold my own just fine with all the rough and finish carpentry that needs to be done. That's not even counting any specialized education/etc (IE I'm an electrical engineer etc) - point being, someone with a reasonably keen mind and can use a tape measure, stay busy, and use various saws, is a carpenter. If I had an ultra productive person who I can count on for things like carpentry or drywall, I'd pay them at $15-20/hour and keep them busy.
Part of the big problem, though, is that there's no 'easy' way to determine if I can count on someone and if they REALLY have the skill-set. There's a lot of people that run around talking the talk. When you observe their work - it just as often sucks. With regards to licensing/union 'ladders' - perhaps there's a correlation there between achievement of (for instance) journeyman or years in a union - however even if that was true - there doesn't appear to be correlation between the 'other' important things - caring a little, not drinking on the job, not stealing stuff, etc.
I don't know.
