Both are valid options. The useful distinction is how each approach fits the work required, the expertise available and the way you want to collaborate.

An independent consultant may fit when developers, writers or marketing staff already exist within the business and need specialist SEO direction.
Working directly with a consultant may suit organisations that want to agree responsibilities, communication and ongoing support with one professional.
