What each model actually gives you
A staff augmentation agency Sources and employs a specialist who then works under your direction. Fast, flexible, and the management is yours.
A freelance marketplace You contract an individual directly. Cheapest on paper, with nobody standing behind quality or continuity.
A managed delivery partner The provider runs the work and answers for it. Slower to start, and it does not add to your management load.

Five questions worth asking before you sign
Who manages this person day to day, and whose week does that come out of? If the work is late, who is accountable? What happens to the knowledge if they leave in month eight? Am I paying for hours or for output? And if my scope grows, does the agreement change or does the capacity?
The answers separate the three models faster than any price comparison.
Agencies selling the first model usually market it as IT staff augmentation services, and the commercial terms are worth reading side by side with a managed agreement before you sign either. Where the work is continuous rather than a contained gap, a dedicated development team is the arrangement the questions above tend to point towards.
