If it was that overgrown all over it'd be $200 for the first cut. $40-$45 per week after that.
Commercial doesn't matter. Doesn't look too big...kind of like a typical residential single family home.
Those prices are with my equipment not a pushmower. Shouldn't change the price though. My opinion is you don't charge more for a push mower unless the homeowner requests it be used when you have better options.
