I've seen those rates before. TPR posted something about them the other day.
When you post exact text, it is not hard to cut and past that text into a web search engine and figure out exactly who you are talking about.
If they're going to put it on the web for public consumption, is there some reason their identity should be withheld?

They don't want anyone to call them ! No one can survey for that price.
There is scarcely anything in the world that some man cannot make a little worse, and sell a little more cheaply.

What's a PSM?
In Florida, are all Surveyors Mappers too?
Searching for the text results in more than one firm (or one firm with multiple names?)

What's a PSM?
Several years ago the great State of Florida (in one of it's fits of infinite wisdom) decided that Photogrammetrist's were every damned bit as good at surveying land from aerial photographs as surveyors who actually "surveyed" the site on the ground.
Thus "PSM", or Professional Surveyor and Mapper. Makes sense don't it? 😉
What?
So can a photogrammetrist perform boundary surveys?
What?
Yes, but only if they willing to do them for $240.

I believe that the people who are doing the elevation certificates for under a $100 are using network VRS GPS to establish elevation at the site then run a quick bench run (possible solo laser level) around the house then take a couple of pictures. It is conceivable that they could be in and out in under an hour. Then take an hour to fill out the elevation certificate. So is $85 for about 2 hours of work doable?
I have never used network GPS and I am not sure how good the elevations are that they produce, but I have heard from a number of surveyors here in Florida that it is pretty good.

Did anyone else click the link for ALTA surveys? It proved to be nothing more than a dissertation on alligators.
"Network GPS" vertical accuracy is dependant on the density of the CORS sites. With a large spacing among stations, you can get numbers that may look good but are not necessarily reliable.
Professional work still requires professional judgement. There's no "Easy Button."

It's my understanding that Florida has a pretty dense RTN network. The Florida Department of Transportation about 10 years back started installing CORS stations all over the state (like at least one in every county). In addition, there are a number private network providers that add on to that as well.
That being said VRS GPS sounds like the magic black box with the "Easy Button" to me. All you are measuring is a vector from this "virtual reference station" that is always with you what some computer has modeled for you from the CORS stations around you. Very mysterious. I guess the guys in the white lab coats say its good. Not sure how you check it.

If CORS in your country is similar to stand alone RTK base/rover setup then I would say that elevation from them is pretty accurate.
Remember that you are also using RTK elevation values for topographic survey & bathymetry survey. If they are reliable for those purposes then the Z-value from CORS is similar to RTK Z-Value. I would just make the distances from the stations to be minimum as much as possible to minimize Z errors.
