Now when I say free, I don't completely mean that, let me explain. My background is film post-production. I even have one of those pieces of paper that my teachers said I should get to prove it. But no one is a creative field
really cares. I don't know how many free gigs I did, before I got a paid one, but it was more toes and fingers then I have. The difference between accounting and this one (and their are a lot, but we are just going to focus on one) is creativity. By having more knowledge then me of the software is one thing, but If can show you twenty free events I worked on where the other guy can only show five paid events, experience is always going to win out. If this is something you want to do, you should never not
be doing it, free, paid or by yourself.
The other large piece here is your client. Is this VJ in your city, or where I am for the next few days, http://www.sapandasug.com/
Let me tell you, we have very different price schemes for who we deal with.
At the end of the day most people think what we do is just play with some software and a projector and if they had enough time in the day they could do that too, no price is ever going to be the same from one client to another. Good luck.
