I work almost full time as a figure model for artists and photographers. Having been a model for over 20 years I can tell you that is bout much more than just wanted to get naked!
It's hard work, physically and mentally challenging, especially when working a 3 hour gesture session!
However if you are interested then the best thing to do is contact the local art schools, colleges and even the local school board.
Check craigslist as well, as there are some opporunities on there, but be careful who you meet up with!
all the best
I am a local model in Edmonton. I found a add in our local weekly paper and I was in. I don't do it much as they have enough models. What I have not experienced yet is model with an other guy that is something I look forward to
