Speaking as someone who has mowed a large church for over 3 years solo I would advise you to not bid it unless you have no other avenues of income. Why? Because sooner or later the church will fall on hard times and ask you to lower your rate, all while assuring you that this will pave your way into heaven. Or, the more likely occurrence will be that someone in the congregation will fall on hard times or get laid off and there kids will be starving and some do gooder at the church will recommend him to do all the mowing till he gets back on his feet. Simple rule of thumb to follow: never work for doctors, lawyers, or clergy!
