When models start out, they seem get various unsavoury offers of work. But there also may be perfectly genuine offers among them so you may have to start with a little weeding.
First, have a look through the profiles of the better photographers and decide what you would like to do - glamour, art, fashion, lingerie etc. - and what you think you may be good at. As above, contact a protographer whose work you admire and ask if they would be interested in a TFP shoot. You get paid not in money, but in images. These are key to eventually building a portfolio of such good pictures, that photographers will be queueing up to work with you.
Talk to other models - there will be loads in your area - and read the help and advice section here. You are pretty with a lovely smile. As Paul says, you should have no trouble attracting offers. Just make sure they are the right ones. Enjoy it and have fun.
if you need any hep sorting through the unsavoury from the genuine offers that will help your portfolio please give me a shout. Always happy to help advise new models to help them stay safe and go in the right direction!
Speak to Chrissie above, most photographers will do absolutely nothing to help your ambition and many will just waste your time. Equally, you will have to make a real effort to put together a great portfolio in terms of time, travel and money and the effort you add to the process will really count in the outcome. Modelling full time for a good wage is not common, especially on the long term, and you'll find only those who offer something unusual or exceptional and are both hardworking and switched on, actually manage it.
But, if you're smart, and ask advice of experienced models, you just might come away with somethiing you'll be proud of for a lifetime ( see my first sentence ) enjoy.
