I need a professional photographer for event on Friday 28th July (Speaker Conference)

Hi. I need to find a photographer for an event I am doing on Friday 28th July from 12-5pm. It is conference set up similar to Ted Talk so there will be speakers that need filming whilst on stage as well as the audience. This is not a remote job and will be on site at the British Medical Association in London (BMA House) Please give your best quote but please keep in mind we are doing this with NHS England funding so have a budget in mind. This would potentially lead to other work with us as we are looking for partnerships not just one of jobs. Thanks. Kerrie
