Yeah, maybe a bit much. You have window washing on one column and window cleaning on the other, don’t think you need both. I’ve heard that having too much on a business card can be unpleasant to the eyes, but I’ve also heard the reverse and using them as a small flyer type. In my opinion I think having a busy back with a little more detail as to what you do and a very simple front is a good balance. The front gives out your contact information as well as what you do, and the back gives those who want a little more information, but don’t have the time to read some long flyer.
