Flagstone border prices

Hi Don,

I live in Scottsdale, AZ. I currently have a brick border between my grass on the inside and rocks surrounding it. The bricks need replacing. I would like to find flagstone that is approx: height = 1.5", width = 6-8", and length >= 10-12". I will also need it to be delivered.

Also, would you recommend a sand or mortar bed under the flagstone?

Thanks for your help,
Steve
