Thanks for your interest. Marketers Without Borders is to help smaller companies and startup, who normally operate without much sense of marketing or any money to spend on marketing. I assume that some well-off retired marketers might be happy to volunteer time to help such smaller companies and startups without charging at all, or only to cover costs.
We can’t assure that the marketing advise is first rate, just as we can’t assure that a doctor with Doctors Without Borders will be first rate. On the whole, most of the outcomes will be favorable to those who welcome the assistance of a volunteer marketing expert.
