I assume a DIY job?
Sod comes in 10 square foot rolls (2X5) for about $3-4 per roll. At that low of volume; assume $4. So $120.
Then of course there's any prep like loam, peat moss, and Scott's Turf Starter.
Edit- a few places to get you started for where to buy:
In the South-
Spruce It Up
In the North-
Blue Grass Nursery
I also keep seeing signs at Burnco saying "sod supplied by Company X", but haven't seen an obvious place where the keep the sodding sod.
