As far as paypal and the rest of the world should ever know and be concerned, we [artists] are "Freelance Illustrators for Independent Clients and Small Businesses"

What that freelance illustration work actually entails is none of their business. Might as well put everything under NDA.

Clients meanwhile as "Interested financiers of the arts and varied entertainment media"

This is all completely true. I hate to be gross, but artists and clients need to "Think more corporate" about their stuff.
