i have just put in a bid to mantaine new homes for a biulder in the atlanta area.they keep around 50 to 75 homes year round.i gave what i thought was a fair bid. now they want me to give them a bid to through out some weed and feed for them. I'm just not sure how much to charge them. I know what the cost will be.time, materials, etc... but i have no idea what the others are charging in the atlanta area. any suggestions ??
