Help me with Marketing

We have launched a new in-house events programme at our venue in Camden (within 10 mins walk from the tube station, but the venue is not yet well known for arts and culture programming). The first event we have established, in association with a well known comedy management company, is a monthly comedy night on the first Friday of the month. Each night consists of 1 very well-known act as MC, 2 medium profile acts, and 1 lesser-known act. The event space holds up to 400 seated, and we are looking to sell tickets at £10 with an £8 concession. I am offering 15% commission on total ticket sales as payment for marketing, promoting and filling this event, with the opportunity to not only work on this project on a monthly basis, but also to work across the brand on burlesque, comedy, cabaret and live music events as our sole external marketing provider. The brand has Twitter, Facebook and Instagram pages with some low levels of engagement already in place, as well as a website/holding page online. I would like to find a freelancer who has worked on similar events before within the arts field, has a lot of experience in social media, online and digital marketing, and can send me examples of previous projects they have completed.
