You are correct about me not owning an edger, weedeater, or blower, although I do realize the importance of having these basic items, so I'd probably look to purchase them early on.
Another thing I'd be worried about is the image that would come with showing up to accounts with a mower sticking out of the back of my car. It seems like many homeowners look down on these sorts of laborers, people with no signs, shirts, or phone numbers to be seen anywhere on their person or truck (car in my case).
What's your opinion on that? Will I be scoffed at or belittled at first glance when the homeowner sees me drive up?
