Around here survey costs depend upon availability of existing established survey points - full corner, half corner, quarter corner. My property was last surveyed by US Geodetic Survey in 1890 for homestead plots. All corners were marked by either capped marker or blazed tree with inscription. I have a meet/bounds description for my property. Subsequently three of the four corners have been established by capped markers when folks were surveying adjoining properties.
The only reason for a current survey is if the transaction is going thru a financial institution and then they will, most likely, require this. Most all properties in my area are established by the old Geodetic survey because they are still very large(greater than 360 acres).
I would say the price quoted to the OP is quite reasonable. There must be established & marked points close to the property that the surveyor can bear off of.
