Land Survey crews from the better known companies would charge in the region of €600-800/Day for 2 man crew and Total Station / GPS equipment. So that would suggest around 5 days on-site and a day's processing in the office.
Doesn't sound that bad but i'd get another quote or two.
It does depend on the level of detail required, features to be picked up, grid spacing for contour generation, location, urban/rural etc. etc.
Where is the site? Is it for planning/design purposes?
