I wanted to follow up on some other ideas that came to mind. Earlier, someone mentioned to specialize in a certain area of junk removal (commercial or yard waste as examples). That is certainly a good way to build yourself as a brand. To get an idea of what is in demand, take a quick look at what's being thrown out or offered for free on your local CraigsList ads. If you notice a trend, consider that as a specialization for your junk removal business.

It may also be worth looking into creating a quick post in services offered in CraigsList to get your name out there. Since its free, any sort of response is profitable.
