Same as the other responders... we got the mailing too, followed up on it and decided to go in just to see. We got a creepy feeling. They wanted the money up front to pay for the photo shoot for the portfolio, then an annual fee to be on their roster. Also, if you are called for a casting call, it would basically be a day spent taking your child into Manhattan (at your own expense..tolls, gas, parking, etc) and then you are only paid IF your child is chosen from the 100 others called in for the job, and if chosen, the job may pay $50-$150!!! So, no college tuition earning there!
My advise, stay away.... dont waste your time.
