Cost is gonna depend first on the mix your using then on the yardage.
What is it for, drive, patio, slab, footer, wall, basement . . . you get the idea.
Once you figure the type of mix you need then your looking at having them load 6.5 to 7 yards just to be safe.
What does the ground look like where the truck has to go. If it's muddy you might want to split it into two loads too, it gets real expensive to pull out a stuck mixer unless you have your own equipment (most of these guys have driven for years but few of the guys around here wheel and they get stuck off road way too easy)
Also keep in mind that you only have so much time for each yard on the truck before they start to charge extra for time too.
That price is right around in the ballpark for most of what we do too.

Here's a good calculator

Hope you know how to run the chute and give commands to the driver. Or you could hire a pump guy and his pump. That's usually about \$100 for a 9 yard load or less. You will also have to tell them you want a "pump mix". The pump mix has smaller rock and is usually a little more watered down.

Now you know where the term "The Whole Nine Yards" comes from... Even though concrete trucks will hold ten yards, they only carry 9 max so it doesn't spill out while traveling up hills. With steep hills they only carry 8 or even less if it is really steep. /forums/images/graemlins/waytogo.gif

Cali has such small trucks /forums/images/graemlins/histerical.gif

I ran 12 yards on a regular basis in my mixer!
A good driver can keep it in the drum, wet, overloaded, and going up a steep hill.
I never spilled a bit until I got rolled./forums/images/graemlins/doah.gif

As for the pump, unless it's a trailer pump they can handle the standard mixes no problems. We use them (the big Schwing's) on a regular basis for footers and walls that we just can't safely get the mixers to. If the pump operator knows what he's doing and the guys pouring the concrete are good then it won't have to be any wetter than if you were to pour it down the chutes.
Talk to the driver first and have him show you what hand signals he used to using and just go from there!

Here's one of our rigs and a my first job on a pump last year.

(500 x.33)
--------- = 6.1 cu yards.
27

Forumula to figgur concrete.
500 is the surface sq ft of the area times X .33= how thick.( 4" is .33 of a foot. 6" is .50 of a foot. 3" would be .25...... and so on)
Divided by------
27. The number of cu feet in a cubic yard.
