runway or print.... there are many different types of models,catalog, runway, promotional, anyhow, all pay well, the money is easy , but not always consistent, it did help me through college! good luck....go through a reputable agency and beware of these so called agencies that tell you to have a portfolio or pictures done ,through their connections at your expense.these are typically scams. if they like your look they will not ask you for any monies for anything...they will pay you the money.
Sj, I see by your profile that you are 17, so you will need (and want) your parents to be a part of this. I am a pro photographer and have shot photos of models. it is a good idea to have some shoot photos of you actually modeling..about any cloths will work for this. close shots, long shots, etc. I would do this outdoors, in natural light. put a 8 GB's card in the digital camera and let 'er rip...shoot hundreds of them and immediately delete (on the computer) those you don't like. print some of the photos you like; 5 by 7" or 8 by 10" and put them in a album. with your parents or legal guardian, show these photos around. there is, and always will be, a huge demand for models and great photos of them modeling; be it clothing or any number of things. my last comment is this: I would never allow anyone shoot a photo of me that I wouldn't gladly show my grandma! lol. you know what I mean. best wishes and stay safe...:-)
