What type of sales position would you recommend for and why: (a) a four-person gastroenterology practice that wants to maintain strong ties to its primary care referral physicians, (b) a medical device manufacturer for orthopedics that is trying to penetrate a new market with a new line of titanium shoulder implants and a new line of pediatric knee replacements for children who have suffered major traumas. These are extremely technical products that will require extensive education in the office and surgical suites, and (c) a health care data management firm that provides a program to hospitals for billing and quality assurance??
