Ok, I'm about to embark upon legalizing my whole in-home operation. I'm planning on getting a real, honest-to-goodness business license and all that goes with it.

What are the caveats here? What are some book-based/online resources for more info on setting this up? Obviously, there are specifics to where I live on this whole thing, but what are the general pitfalls and problems and good things I should look out for here?

thanks,
Rich
