You pick the people you work with Ian, I expect you sort of know who will make a go of things. Mentoring someone like me would be similar.
I reckon I've got the drive and marketing skills to biuld the work up. Copies of your standard contract would be helpfull ( it might be best to copyright these so that people like me have to pay). I don't expect they are absolutley iron clad, but better than nothing, and I bet months of work and thought went into them.
You'd have guidance on who to pick and what levels of investment to ask for.
I wouldn't be after making a quick buck, but long term providing six to ten people with lucrative businesses that they couldn't achieve on their own.
I wouldn't give any talk at Windex, but that's just me, your idea is a biggie.
