9 X 34, oh the joys of living in the city.

it's true, but we do have grass in front and a 50x50 lawn on the side.
And why will the grass not grow. There has to be a reason. Over hanging trees that need to be thinned out, poor soil ECT.
a) I live in WA, so most of the year there isn't really direct sunlight giving the grass much anyway, though watering is normally not an issue until August. b)it is adjacent to the house and has a 8ft fence on 3 sides blocking the little light it would get. c) all but about 1/3 of it will grow in the summer pretty well, but the rest of the year its just too muddy to want to use.
A sold concrete back yard would be a huge turn off as a selling point.
You may think your going to save money by trying to do some of the work but once you figure out just how much is involved to cut it up, remove and and poring you will soon figure out your way over your head on this one.The further i get into the research phase it looks like the demo/prep work will be done by myself. Leaving the setting up and finishing to the professionals.
What you see in that picture is stamped concrete. It's pored and a rubber stamp is laid down and jumped on to emboss the look of stone. It can be done to look like brick, slate, stone etc.
So far local bids have come in anywhere from $11,500 down to $1,100.
I don't want to take the cheapest just to save money and not be happy with the results, but I also don't want to pay an exorbinate price on the same work. Just wondering what a middle of the road bid would be.
