On Field- Shoppers Recruiting in UK

I am looking for someone who lives in the UK and can hire participants to record a video (2-3 minutes) in a supermarket store such as Tesco, Sainsbury. Participants have to record their video while they shop for a specific category requested by us and answer a few questions as given by us in an instructions document- while they record their shopping experience. I am willing to pay £20 per video up to a maximum of 50 videos. The attached document is a sample instruction for recording a video. Please reach out to discuss any further queries.
