Hi,
I'm a pro videographer/editor based near London and happy to discuss your requirements further. If we can have a chat about the activities, whats needed to be recorded and then the edit requirements as well I can work out the scope and give you a price. My rates are typically from £400 inc. expenses (+ freelancer fees).
If you had a date/time set for this shoot as well please let me know so I can check my schedule.
Thanks
Khalid
