i was asked to bid on a property thats bigger than ive ever bid. the lawn is actually in very good shape, customer wants to stick to his routine of dethatching every 3 yrs. there is minimal that build up. the property is 25,000 sq. ft of turf. flat, level. i use a billy goat thatcher. no seeding, just thatch, clean it up, and haul it away. any price this?
