Anyone lay their own concrete?

My shop 42x96
Electrical trench 11K
New meter electrical to shop up grade house meter 26K
Concrete 38K
Structure built 127K pole barn and since purchase price has increased 3 times
Spray foam closed cell 30K
I will do what i can so save close up inside electrical inside shop, gravel around shop but time goes fast just like money. I’m paying to get most work done by others. Money will come and go but i want to retire soon 5 years and i dont want to worry about it then.
