I laid my own
I did 2 seperate 10x20 slabs then the contoured/ tapered section that ties to the original driveway. I graded it, put gravel down, and framed the sides with 2x6s. I rented a bull float the first time, but just bought one and some extension handles.
I had called for some quotes and they were all over the place.
I've got ~$1400 in concrete, $120 float, $30 hand tools, $30 lumber, $40 gravel.
I was very nervous the first pour, but then got more comfortable with it. I learned a few tricks by the time I was done. I'd say my job is an 8, and it's definitely better than my original driveway, and I can happily say I did it myself.
I broom finished it for traction and did a simple edge like you'd see on a sidewalk.
What im saying is, with some work you can do a decient job your self and save some $$..
