Briguy,
As I always learn so much from this board, I'm glad to contribute a little professional advice to others here. As a Michigan Licensed Professional Land Surveyor, I know mostly about Michigan laws and practices but your situation should be simillar.
Survey costs are not necessarily based on the size of the property. Like any service business, surveys are based mostly on the man hours and materials. The legal description of your property as contained on your deed is the "set of instructions" a surveyor needs to see before he can bid a price for doing the survey. The description (usually) tells us the size and shape of the property and how it fits with the rest of the world.
Bidding on a re-survey is difficult, from a Surveyor's point of view it is difficult to tell wether we can drive up to a site and find all the previously staked corners with a metal detector, or if we have to run several miles worth of traverse first. Even if we do find the corners, we would still need to measure between all of them, before we could confidently state that they are in the same position as they were originally staked in.
If you think that price is too high, call the surveyor and ask why. If you're still not satisfied call another one. The most important thing is that you are satisfied with the service you receive. As with any service, you want to know that they will be there when they say they will , charge you what they say they would, and be there to answer questions should issues arise with you or your neighbors.
