Davie,
yes I have taken clients out for the last 25 years, mostly overseas clients and in particular americans. I have always charged for the whole week, to include all accommodation, food, wines, transport, licences, sightseeing, fuel, stalking and trophy fees. If they got lucky and shot a medal Fallow, Red, Sika or CWD I charged no extra.
However with Roe the charge was to include up to a Bronze quality head, anything over that was extra.
I have taken many out from the SD site, some charged for at £60 a stalk, no kill fee on doe's/hinds. During the Roe Buck season I charged £50 a stalk and a £25 kill fee for all cull bucks, however I allowed a guy to take a very old bronze head for the same charge last year.
Best
Malcolm
