4/5 hours filming in central London on 7th January

I'm looking for a video cameraman with professional equipment to film two short introductions by non professional presenters in the offices of a charity near Islington, London on 7th January. I also need to record around 2,000 words of voice-over at the same time so would need a reasonable mic. The recording needs to be done to a professional standard and I estimate the work would take between 4-5 hours.
