Wanted little kids as shoe models

We are an e-commerce company selling kid's shoes. We are trying to shoot some short videos and photos for brand promotion. Now we are looking for 2 kids (one girl and one boy) with shoe size 13 to be models. The shooting time is about 2-3 hours. We will pay $100 for each kid. We will sign a contract with the guardian of the kids so that we the content can be used for commercial purposes. If you are interested, please contact me, and it would be best if you can attach a photo of your child.
