Far as I know its OK to sell some thing industry related.
If some one were advertising their company's services or mass produced product then thats a different story and would fall under the advertising guidelines.
Professionals are people who can do their job when they don't feel like it.
Amateurs are people that can't do their job even when they do feel like it.
