You mentioned that you were going to dispose of the grass clippings/debris on your property, do not get in a habit of doing that unless you have a canyon to fill, find a yard debris recycling place and find out how much they charge per yard and charge for that, plus your time to unload it, I take mine to McFarlane's Garden Center and pay about $6.00 a yard with my senior discount, if I had been dumping it on my property, my house would be completely buried by now.
My trailer has the name of my company on the side of it with big letters/numbers so all can see who I am and what my number is, I also have cards and flyers, I even had a sandwich board sign I used to carry around with me that I stood up in the front yard by the road so folks could see who I was while driving by, you need to make sure everyone can figure out who you are, I have folks taking a photo of the side of my trailer all the time.
I used to pass out flyers to all the houses near the job I did that day, it only took 10 minutes so it wasn't a big deal, but once I was booked out more than a month ahead, I quit passing out flyers as new customers don't like waiting that long, my regular customers have gotten used to it and call me way ahead of time to get their day scheduled.
My sandwich board sign which I have not used in years, it's falling apart.

My trailer sign which came off my original work truck.

Here is my original work truck setup(Datsun work truck), with the sandwich board on the trailer where I kept it.
