Impressions based solely on the list as shown... It's too cheap.
The signs to me point to very old equipment, or ignorance of modern methods, inexperience, or all of the above. You will get what you pay for and for some, that's the most important variable.
I recently walked through a shop that I haven't dealt with in 20 years. Some of the equipment is the same thing his father had, and it was oldschool in the 80s. Skill or not, eventually things wear out, and as technology improves it's more accurate and takes less time to do better work - but you have equipment payments. So generally the costs go up, or should, just like everything else. In my experience shops go under for one of two reasons: the owner(s) are not as good at business as they might be at machining, or because the customer base believes it's in their best interest to find and buy cheaper at a distance rather than pay a local shop a fair price for quality work. It's like the Summit Racing effect on local speed shops. Or Rock Auto. Or Blueprint...
