I gave a quote for preping (rockhounding) and hydroseeding a 21k sqft lawn, front only. My price.....$2300.00. I get it ok'd and the next thing you know he's calling me back cancelling and going with another company that came in at $1500.00 AND adding top soil AND going around the sides and back of the house w/ rockhound and hydroseed adding another 5k sqft. This guy is going to have 700+ bucks just in materials, plus the rockhound for at least 6-8hrs then manual labor. At that rate this guy cant even work for peanuts just the shells. But whats a normal profit mark-up on a job. I thought I was ok at around 25-30%.
