This is a website that allows you to put up a profile and then submit on modelling jobs. The company acts as your agent and takes a fee on anything you book. The jobs seem legitimate though I never submitted to any. Here’s a discussion about their legitimacy. I was a member for about a year but stopped when I realized they never do acting roles.
This claims to be the world’s largest modeling community. They do seem to have models and modelling opportunities all over the world. They also have modelling related crew positions like Makeup Artists and Hair Stylists. You can browse the models and jobs without logging in. You can only see the real details of the modelling gigs after you log in. They have a great page on how to avoid scams when looking for work. They have a whole free education section that looks like it would be a good read if I was a model. Their site looks nice and fun to use – I wish they did acting jobs.
