Collection of simple images of people doing various actions in-front of a computer

We are collecting a set of images to train an artificial intelligence model which can understand actions people do while working in-front of a computer. We have a pre-defined list of actions which you have to take pictures while doing the action. We are planning to recruit 1000's of actors for this purpose. Each actor has to submit 112 images of 112 actions. The background has to be changed when the actor changes. The payment will be for every successful image you submit. Please quote the price per image. We have attached the guideline and samples to this request.
