Push mowers are $65 ($75 if they’re extra-wide). ~ 1 wk ish turnaround time, and they ask that you remove the handle.
Rotary blade (most electric and gas mowers), you take off the blade and bring that in, and that’s around $15 and is shorter turnaround (~ 3 days or less)
Loppers, pruners, shears, etc, ~ $10-12 each, give-or-take, based on the size, and they are 1-3 days turnaround time.
