I get a fair number of emails from people looking for modelling jobs. I wish I had more oportunities to offer, but I do try to keep every model's info on file, and use 'em if I can.
One thing I'd like to point out to anyone who's looking for this kind of work: include a picture!!
I generally use models I've worked with before, but I do consider anyone who's available, particularly in the summer, when some of the models are out of town. But it's uncomfortable to hire someone sight unseen. If nothing else, it helps a lot for us visual people to have a face we can associate to the number.
It's pretty standard for actors & other kinds of models to attach a pic of some sort, and nothing speaks for you like a visual image. It needn't be a professionally shot portrait, or a nude pic, either, just a good looking snapshot to stick in the memory.
