Yes, I'm 74 but fortunately thanks to a parental lineage of a healthy genetic structure and keeping myself in reasonable physical condition, showbiz is not an issue. Allowing my marketing and branding assertiveness lapse has proven to be an Achilles heel. Out of sight, out of mind. The lesser the numbers of bodies I perform in front of, the lesser the numbers of people know first hand what they're getting.
I have had an Event Production Assistant for 5 years (dislike the word "roadie") and the key is paying him well. He doesn't stay at the events and does not want to be a DJ. To me, that's the nugget. Anyone wanting to be a DJ wants lots of money for little effort. Hell, it's what attracted me.
My EPA get's paid $15/hour and the clock begins when he leaves his house so that he is reimbursed for his drive time to and from the event. After setup, what he does and where he goes while the event is happening is his own business. He does not stay.
So, an average local event within 45 minutes (most are less), a 45-minute setup, a 30-minute breakdown, and a 45-minute drive home equates to roughly $45.00. In order to ensure his reliability, I guarantee him a $60.00 minimum rate even if the event is next door.
My wife is not invited to my workplace. I don't go to hers. We're even. (unless it's an out-of-town road trip, then we're together but still not at the event.)
