We have an oppritunity to bid 2 cemetaries. Both very large, around 40arc. Would like to run a crew of 5 w/ 2 60" Super Z's and 3 trimmers. What they want is service every 10 days. 1st service both mow and trim next service just mow next mow and trim and so on. Can anyone give some help on man power, time and price? Thanks!
