Colorado Springs property line markers

[James Ross]

Hello, I'm in Colorado Springs and looking to get the property line between my property and the yard behind it so that I can put in a retaining wall and ensure it is on my property. I've been quoted $1100-1300 for this which is three or four times what I expected.

Does anyone have a good surveyor in Colorado Springs or know what a normal price is? Home advisor quotes $344-676, and my lot is much smaller than some of the larger lots they have further outside the city, so I imagine it should be on the low end.
