What you're looking for is pretty hard to find in terms of a marketplace. What you're most likely looking for is just a really good software agency, but it's not always easy to figure out quality. If you're a well-funded startup, I'd maybe reach out to investors/portco network to see if they have good referrals.

Outside of that, the closest marketplace I know of is a.team. They are basically forming software/development/other role teams for you. However, they haven't necessarily worked together before.

And then of course there's the opportunity to acquihire a tiny company, but that's probably way more effort than you're looking for.
