I get a lot of emails and phone calls about this so I'm going to tell you how we do this for a basic job. Please don't email me and tell me that's too cheap or too expensive, etc. I'm just trying to give you the basics here...
For a Bermuda sod job, laid with mini rolls, I will price the lawn at just about double how many pallets it will take. For instance, if it is going to take 27 pallets to do the job, then I'm going to charge somewhere in the neighborhood of $5400.00. I pretty much follow this rule for any basic sod job using Bermuda (that's what we do the most of). You'll have to play with the numbers for your area to see what works for you but this should get you started.
Here are a couple of other articles on sod.
