I will not leave the house for less than $250.00 for a four hour gig ,and thats if I play two consecutive nights or more.One nighters are a different thing completely.certainly worth a lot more if it's a one of like a wedding or a special event where your talent makes the difference in success or failure to the organizer.You are a professional and should be payed as such.You don't get cut price plumbers or electricians.Anybody who has taken the time to learn their trade and invest in the equipment needed to perform it should be compensated the same as any other business.Musicians/entertainers are not a dime a dozen.It is specialized work involving a lot of study and practise,and not something that can be done by just anybody.A friend of mine says.If you pay peanuts you get monkeys.Iv'e seen some pretty entertaining monkeys,but never one who can sing and play,and set up and tear down.
