I used to have a landscaping business and was chatting with a guy about business names. I know some people like to use a name that puts them on the top of the phone book. Less relevant these days as people Google instead of using phone books but if I was Adams Landscaping I would probably be at the top of the landscaping category.

Another thing I heard was never do a name like K&J Builders, it's not memorable at all and if someone goes looking for you later they'll probably find a bunch of two letter names and may accidentally pick someone else.
