Just the concrete in this valley would be $2k and that doesn't include having a reasonably competent fellow have the grading and forms done before the concrete gets there. Or just dump it in a pile and flatten it out with a tractor :rofl:
ive formed and poured more concrete than i can count. I'd do it myself. Concrete for that would run me about 1200 for 8 inch thick, M70 grade. but i get a BIG farm discount for it or it'd be about twice that.
