I have been self-employed as a writer/marketing consultant since 2001--with only a 4-year break of employment (with a previous client). I'm back to working for myself but would like to work onsite as a contractor for different companies. When they see my resume, they "question" my experience, or ask "how recent?" One recruiter said his client thought being self-employed since 2001 meant I hadn't WORKED since 2001! I have a company name a company website, client references--you name it. Why would someone (a company) question a professional writer's credibility just because she works for herself? Any suggestions on how to "validate" that what I am doing is REAL? (Maybe I should add client testimonials to the paragraph? I already have "Special Accomplishments" listed.) Thank you!
