Need some help with a marketing questions (Sales Management) below.

A number of organizations that did not consider marketing part of their business activities in the past have found the need to begin to market their services. Nowhere is this more prevalent than in the nonprofit community. While not selling a product or service, public service organizations such as the Red Cross have developmental officers who market the organization in the community. (a.) How might you sell a public service organization in the community? (b) What is different about this versus selling for a for-profit enterprise? (c) What would be your goals and how would you accomplish them?

Thank you,

Amber
