I've never put any of this stuff down before except a few feet here and there. Customer wants me to install that black plastic flower bed edging that comes in big rolls. I know I have to dig a little and put stakes every few feet in this to hold it in place but what is a decent price to charge for this. Its just under 400 foot total that has to be installed. Customer already has all the edging and stakes to drive in the ground all I'll be in is just regular dirt/mulchy ground no rocks or roots so the digging will be easy enough. Thanks in advance for any advice.
