Researcher to find Restaurants in the UK that have a great videos on social media

Geographical areas: UK
Data to include: We need a comprehensive list of the Restaurants in the UK (preferably London) that are using video as part of their social media marketing. This means that they are actively and regularly creating and posting videos on their social media channels (at least one video on one of the channels per month) - specifically Facebook, Instagram, Twitter and Youtube/Vimeo.

We need the name of the Restaurant, the link to the social page(s) that feature the videos. We also need the name of the restaurants that you check that don't have any social videos.
Extra notes: It's important that we record every restaurant that has been checked so that work is not replicated.

I've posted a fixed rate of £100 and a target to check the top 500 restaurants in London. We'll provide the list.
