If I were him I think I would start off by doing one of those evening courses in setting up your own business. There is alot to think of- tax implications, accountants, solicitors etc. I wouldnt want to go into it completely blind. A fair percentage of new businesses fail in the first 12 months of trading I believe these courses help you avoid pitfalls. If not an evening course, Im sure there are books he could buy. Sounds like a fun business though I wish him luck !
