suitcase provider
n.— «The vast majority of these are very small—in many cases, one-person enterprises or, in the vernacular, “suitcase providers.”…The traditional view is that a “suitcase provider” is a bad thing because it implies someone who is a fly-by-night. Usually, though, they are people who have worked in a profession for many years and provide training through mentoring and coaching.» —“The Skills Supermarket That’s Virtually Everywhere” by Jim Freeman Biz-Community (Cape Town, South Africa) Oct. 10, 2007.
