I saw your craiglist flyer you posted. I actually like it. I made up something similar today. link: https://post.craigslist.org/manage/2795626937
I think if it looks to professional/over done it could be a turn down to some folks. They might feel that you will charge them a lot unlike the guy who has a smaller business down the road. I know that communicating with your accounts makes a big impact if they will hire you on again. When i worked for a large landscaping business doing maintenance they never talked to the home owners. Some of them don't like to be bothered.
Do you have a business plan? If so i was wondering if i could look at it to see how it is written. I want to be ready if i get enough accounts this year i can get a loan quickly. I should have one regardless.
