Hey guys i need help on a bid. Its an area roughly 25x50 with a few large trees. Area needs topsoil built up and leveled and built up around trees. Whats a good depth of topsoil? How much topsoil will i need? What should i charge for topsoil at 18 a yard screened and a 20 delivery fee? All the soil will be dumped in the drive and have to be wheelbarrowed in by hand. Any and all suggestions will be greatly appreciated. Keep in mind i also need to buy seed and straw. This is only half the yard the other half will be done in fall if we get this part right. Thanks guys.
