I only have one commercial property, but what I did was walk the property with the person who was "in charge" of the hiring. I first listened to what they wanted done... ie: bi weekly, bagged, trimming hedges only at first and last cut. I then began to question him on why he wanted this and he said that those things should bring the price down. I explained to him that the property wil not look as well, and will be almost the exact same price as I charge 1.5x for biweekly. I submitted a bid for both what he wanted, and what I suggested, and thy went with what I had suggested even though it was and extra $175 a month. I know this may not be possible for you guys, but it worked out well for me.
