Be VERY careful and wary. If anyone ask you for $ it is a scam. You Do NOT need professional shots taken.
I've modeled most of my life. It is a JOB and it is brutal. It would be hard for a 7 yr old because there is a lot of rejection and that = not good for a child who is not very secure with themselves. SO many moms believe their child is the next big star and beautiful... agencies see tons of children and yours is not always the one for the job they are looking for.
The job itself is very demanding... missing school for casting calls, small jobs, etc.
Just think hard before you jump in with both feet. Remember that it is a job and any $$ your child makes should go straight to a fund for your child.. they are the one working.
My daughter also models but it is limited. She models when she is called upon... we do no casting calls, etc. I am not going to submit her to that. I don't even do casting calls... I only model for people who know me and book me ahead of time. Again.. it is ruthless and brutal. You must have a thick skin and be able to accept a lot of rejection. That is hard enough for an adult, much less a child.
