I used to do data recovery but lost interest for many reasons (time consuming, hardware required, software required, etc.). I wasn’t doing this as a business, but more of a favor where I sometimes charged. This made the expense to me not worth it. However, I just heard of $300 Data Recovery while browsing YouTube. These guys seem pretty legitimate and their price is quite low. I wouldn’t do this work that cheap. If you need data recovery, check out this company and this video on YouTube.

UPDATE 12/19/2018

I used their service a few months back and they fixed a hard drive hardware issue. I was able to recover all data from the drive after that. I am totally pleased with their service because I do not want to learn how to deal with the various issues and buy the special tools. I highly recommend them!
