TFP Shoot for Stock photos site Getty Images

I am looking for a diverse range of people who have a tennis outfit with minimal branding. I want to be transparent as possible, the images are to be uploaded to Getty Images as I am building my portfolio. Unfortunately I do not have budget to pay. The brief requires people to be playing, serving and shaking hands over the net, victory dances and facial expressions (but no high fives) here is a board of the images I'm looking at doing.
