A good agency documents its deliverables, plans for error recovery and trains your team on maintenance. Beware of quotes without a prior audit: a critical project deserves a scoping phase.
Compare minimum budgets, the number of documented projects and the review sub-ratings (quality, deadlines, communication, budget). A shortlist of three agencies is enough to decide.
