Singh is on the other side of town.
Try H.M.S. Landscape (from my notes)... The “Cooked Compost mulch” can be delivered in 11 cubic yard amounts only, for $165 in the Metro-Phoenix area.
Address is 6107 S. 32nd Street (S. of Southern) Phoenix, phone is 602 268-1809
Based upon my experience this is not a finished compost, hence the compost-mulch designation. But it is pretty good for the delivery price. The batch I received clearly had a lot of horse manure in it. But a lot of other compostable material as well. Some material you could still identify the source (hence the not finished comment).
11 cu yds is a lot of material. I would not consider this material ideal BY ITSELF as a garden soil. But that would be true of any not fully composted material. It certainly could age into good soil within a season.
EDIT: This is a zombie link that nobody replied to until now. I hope the OP forgives us.
If you have a truck it's considerably less expensive as you save delivery fee. I've gotten chips there a number of times and that's always free. My favorite type of cost.
They have a few different grades of dirt and even the good stuff isn't perfect. I don't believe I've ever found perfect dirt that can be delivered.
Also - Singh isn't too far. It's just up the 101 which isn't much further than HMS. However I believe HMS is way cheaper for similar quality.
