Basically.. you have to get permession from your parents/ guardians.. and they have to sign alot of papers and always be with you in any good/ permissable company or agency.. Best you can do, is reading more and knowing more about the business before you start.. there is alot of scammers and bad people who just will be after your money or something else.. Read and try to communicate with the reputable agencies.. then you have to start participating at the events at your school, acting, cheering, modeling, and all other activities happening there.. it help alot for your future, and as a training as well..Good luck and have a great day ..
Are you planning on going into business as a model, yourself? I do not see the connection.
