Re: What do you do?
Ok, Lisa, here's what you do:
Step One: Find a bunch of fellow sound tech type friends and tell them you will put them on your "Call List" for when you need extra help
Step 2) Tell your clients that you are already booked, but that you will staff the show with one of your "best people"
C-a Because you are in such high demand, you raise your rates by 50%, then when you need to hire out an extra mixer for a show, you pay them 50% of THAT rate, and you pocket the other 50%
Finally: Now you are profiting on both gigs.
See...you just started a production labor company 
(Of course, there's probably a bunch of legal stuff and accounting and payroll systems that have to be set up, plus worker's comp, insurance, and taxes (which aren't taxes in Australia like 95% or something?)...Better go ahead and double your rates to make sure you have something left to take home at the end of the week.)
