We are looking for Freelancers from Europe to take a Selfie with our Product

Hello, We are looking for various freelancers—young and old, from all different backgrounds—who can take a selfie with our two products. We will send you a nasal spray gel and a mouth rinse so you can take a photo for our reference section on the website. We are planning to create a collage of 100 different customer photos. An example is attached. We need confirmation that we are allowed to use the picture. You may keep the products, of course—we only need a simple smartphone photo.
