Product sampling

Hello! I'd like to invite you to a project I want to do. I am seeking photoshoots of some prototype of products that I am sampling for my website and showcasing for investment. I am thinking of doing 90 photoshoots. I require 3 product sampling models, a female, a male, and a girl model, ages 11 and 14. I require a total of three hours for the photoshoots.
