Miami Tour

I am 18 years old, and I am trying to get enough money for me to go on the tour of South Miami Beach models, its about $ 3,000 by November, it includes a showcase for agents in Miami airfare to and from Miami, transportation, four nights' hotel portfolio, south beach photo session, the preparation of special imaging, before and after the consultation, and training.

Should they be paying you?
sounds like a scam to me.

This is marketing toilet, not a modeling opportunity. If you check the credentials of agents you will probably find they are questionable. You can get images from your portfolio of local photographers. They accept everyone at these things and all you get is a trip to south beach and some photos.

Find an estate agent in your area if you are interested in modeling. You can also list http://onemodelplace.com or http://modelmayhem.com
