Material cost for the 1,900 square foot area that would get pavers:
below is $14.25/sq ft so approx $27,000.
Unilock makes a cobblestone paver called the Courtstone. It looks good and it's $8.49/sq ft so approx $16,000.
This one is also Unilock Courtstone and is just a different color.
They all seems expensive but the $27,000 one is way too much.
