Can I get Arc.dev level vetting with a real team?

Yes, and that is the main reason to consider a dedicated team over a marketplace of individuals. Acquaint Softtech vets engineers in-house to a comparable bar, then places them on your product as a team under a project manager rather than as a single freelancer, at a transparent rate from $22 per hour. You keep the quality signal that Arc.dev's vetting provides, but you add a project manager, code review, QA, and continuity that an individual placement does not include, and you drop the deposit and the conversion fee.
