It takes more than a website, more than a batch of compcards, more than prints to be a model, it takes a lot of work, alot of research, and if you are not willing to do the work then modeling isn't for you.
For any of the social websites that say It's EASY, they are full of it, modeling involves marketing yourself, and you won't be discovered on the web.
You would have better luck printing up some 4 x6 prints, of headshots and a full body shot, could be in jeans, fitness clothing, swimwear, and mailing them to every agency in your town or city. If you are in NYC there are plenty!
If you were to mail all the agents listed in the ross reports, or on Backstage.com you would most likely get a call back, but you have to do the work.
