There may (just) be a tv doc in what you are doing.
Its hard to know where your search will end, could be interesting... or not.
Suggest you contact one of the UK production companies asap so they can shoot you doing the searching. Try Wall to Wall productions or Lion TV...
Generally they dont like "one-off" docs but it may fit in with a series they have planned.
Beware that how you are portrayed would be out of your control.
