I have done similar non drone photo work. Pricing depends on how you feel about it and what effort costs you incur from the “job”. I say job with inverted commas as it might be great fun and for a mate etc. It also depends on what they will do with the images and you might want / need to specify if they can be used on their website, or in a magazine, advert and for how long.
It might be worth looking at things like this video / page - What Should You Charge for Your Pro Photography? for an idea.
I guess if I was doing this as a job, I would consider the planning ( working out where to be when on the course, what looks good on google earth, ties up with sun ), travel, the actual doing ( flying, photographing ), going back a few times to get different shots / better shots based upon a previous flight, then the editing time etc.
Having done weddings, I worked on the biases you needed to charge more than grand per ( afternoon / day ) shoot just to make it worth while ( to cover marketing, editing, travel and shooting, kit, insurance etc etc ) as it used to take a week to shoot, edit and print the work.
Of course, if you get to play somewhere cool and have a free range to shoot then thats different, but its worth while finding out what they expect from the relationship ( ie ten great shots for use on web / magazine adverts( so appropriate size / quality / colour etc ).
Shout if you want any more ramblings from me ( or if your Hampshire based you want an extra pair of hands ).
Have fun and good luck with it!
