I gave up my do it myself septic install and hired out the septic install after I did the trenching, digging the tank hole and a bit of prep on the field, after I had the area was blasted out.
The system is large enough to support a bed and breakfast, maybe even a hotel with a 2500 Gallon tank and 480' of Presby Tubing. Over 35 Tri-axle loads at 22 tons each of sand and stone were hauled in just for the septic.
The installer had his extended family helping with the install. He used a 320 Long track CAT with long stick and 5' grading bucket. I am paying contractor price for the sand without mark-up. Same for tank, pipe and Presby Tubes, etc. The labor charge is $7,000 firm.
If I did the install myself, I would pay a bit more for materials as I do not have a contractor account at the aggregate supplier that has the best sand price. I would still have to hire a track steer for the finish grading. I figure the final real difference in cost would have been $3,000 or $4,000 saved and one heck of a lot of time on my part used that I need to spend elsewhere.
Considering the installer's labor cost included absorbing $1,000 in fuel and transportation cost and at least $500 in aintenance, wear and tear of the 320 CAT, he and his entire family was working for $1,000/day. With the limited number of good work days in NH, your are not going to get rich doing this, especially working for guys like me.
Seems like a tough business.

PS
The well came in less than expected and is a real gusher at 40 GPM. A microbrewery or spring water bottling plant could be supported off this well.
