I tired to shop around but did not have much luck. You are probably looking at about $300-400.
I ended up doing it myself. I did not need a formal one, and was lucky there were two survey pins on or close to my line already. One was a standard penny size one with a code on it and marked on the recorder map, the other was tiny, like a very worn and irregular nail head, and barely visible.
Not the most efficient route, but it was fun.
If it is for a side fence, tell your neighbor it is customary to split the cost.
