Experiences with soil surveys from "Geologen-finden.de"

Hello everyone, has anyone here by chance had a soil survey done through Geologen-finden.de and can tell us how the experience was? We received an offer for just under €850 and have also received offers from other geologists between €1,500 - €3,000.

my 50c. I am in the preparation phase for an assessment before I buy the property ... have called some experts/sent documents. Through this website I found the cheapest one. Also €850 plus soil quality/excavation in case of a basement. The well-known dominant player wants €2,000 to €3,000, the FFH protected areas seller would "mediate" me, he would get €1,450 (and he would surely get a nice kickback)...

I would be interested to know if you were satisfied with the soil report from Geologen-finden.de. thank you
