We are in Ohio and get 4-6.00 per foot depending on what type of curb they want. We do this as an add on service to our existing landscape business. The profits are HUGE and it is very easy work. Cut the sod out where they want it, tamp the ground with a tamp and lay it down. It does require a bit of skill finishing the curb, but nothing you can't handle.
We do not own the Tygar product, but it is a solid brand. We have been very pleased with our equipment and we do about 20-30k a year in add on sales with this. Material and labor costs are about 1.50 per linear foot.
It's catching popularity also. I sell alot of it to retired folks who stay in Florida for the winter.
