Hello and thanks for posting this - love to help you out with this. We actually work with quite a lot of time lapse images for our various productions and our TV shows.
Would I assume that this is 2 days filming then? On ein Oxford and one in London - I'm based in Hammersmith in London, so Oxford is an hour away (my son is there at Uni! ). We work all around the world on productions and have all the equipment you need such as a Sony FS7 camera, mics, and so on - have a look at some links to see what we do and if you feel this is suitable quality.
Not sure where your presenter is from of course, but we have helped a Dubai based TV show for the past couple of years when they visit here - the show is Al Rawi - if you know it, and the main presenter shoots a lot of pieces to camera in Arabic, then watches the playback to make sure it all sounds good.
Happy to help out and learn more about the project you have. Thanks Cliff
