We have topsoil in 40 lb. bags for $1.99. We also have grass seed blends made to our specs. that are best for our climate. There a Sunny Blend for full sun, a Shady Blend for full shade and my favorite called Sandy which is actuall great in all soils but especially good in sand. It can put roots down 2′ into the soil and grows in full sun or as little as 30% sun (anything shadier and you’ll want out Shady Blend). Sandy is fine bladed and low maintenance. HERE’S A LINK to a blog post showing how to start grass from seed.
