Looking for production agency in the UK for upcoming video project

We are looking to make >4 short viral videos to be used as advertisement on Social Media in the UK to promote our mobile application called 'Azar'. Azar is a social discovery platform that matches people with each other through 1 on 1 live video calls. The videos we make are normally around 15-20 seconds, and feature at least two-three models interacting with each other through a live video call over Azar. The whole video can be shot with a (high quality) smartphone camera, as we want it to appear as a screen recording of the main model having a face time conversation with someone they just met on Azar. This way we add a more realistic (viral) feel to the video and it will seem more like a viral video (think Vine) than a generic and boring advertisement. The concept of the video can be fairly simple, but it's important to add elements of humor and surprise. This is because the people who meet on Azar are strangers to each other when they first meet, so the interaction has to feel easygoing at first, with the addition of a sudden/humorous event happening in the background after a few seconds to maintain the viewers' attention (imagine for example someone suddenly walking in on you while you are trying to show off your dancing skills to a person you just met on Azar). We have a lot of concepts already planned, but feel free to suggest some ideas of your own! If you're interested in collaborating with us, don't hesitate to contact me, and I will provide you with example videos to help guide your production. Thank you!
