I had a guy call me for a bid on a residential property. 6000 k, not a big deal, for the front yard that is. The back yard you had to go down a flight of stairs, I didn't count them but it was longer than going to the next floor of a house. Anyways the backyard was down there and I would have to carry my push mower all the way down it. Would you guys do it? Or is there something I could use to do the back yard that is light? How much extra should be charged?
