The variables to answer your question are almost endless and all depend on you, your market and what you want to make.... there is no right answer except for the one that is right for you....
Some are happy making $200/event others $3000+ somewhere inbetween is you. Find you and you will be happy.
Be honest, and call a few DJs in your local area. Explain you're getting started, or new to the area, and want to get a feel for what the locals are getting.
Most DJs are pretty nice folks, and will help get you up to speed. Those that aren't, are more than likely greedy bastards, and will hang up on you, or quote some outrageous figure, so you won't be their competition
In my area of NY, somewhat typical for a 200 person wedding, most seem to be getting between $500-1100. Some of the higher end folks get more, some of the lower end folks get a bit less...
don't decide to raise your rates because of what us idiots say here or on any other chat board... you need to do the research and decide what makes you comfortable and remain profitable... if $100/hr is what gets it done so be it... who are we to decide what is best for you and your company....
You know I actually lowered and raised my rates at the same time by offering a variety of packages...
One Basic
One Upgrade
and
One ubber get it all.
Then there are the add ons that people can get for the Basic and Upgrade packages.... and when they do that the price is higher than the Ubber get it all package... this has the affect of giving the client the feeling of getting more while spending less... and I get what I want for price.
