I've been asked to submit a bid on the grounds maintenance for a church and would like someone to look at my numbers and tell me what you think. I have 1 acre of wide open cutting, a 3.5 acre graveyard with 75% of the stones in a straight line allowing 2 passes with my 62" toro. The other 25% will require some manuvering but I can still use the toro. There are 546 stones combined that will need string trimming around along with 30 minutes of trimming around the buildings. 30 minutes blowing off hard surfaces. Travel time is 1 hr round trip. The average weekly income for the church is approx. $5000. I'm thinking around $315 per cut. What do you guys think? Thanks for your time and have a great day!
