I'd recommend getting a remote, third-party team of contractors, and hiring a fractional CTO to manage that particular team and any related software. Having done that pattern before; it's less liability and cost for you, and easy for you to experiment and get the job done. You can easily end the contract with the team once your software is stable enough.

My only advice would be: don't attach different freelancers to each other and expect the job to get done. That might work in some particular use cases, but most software requires (at least) the engineering team to be in-sync with each other. Freelancers rarely have that skill.

Hiring a full-time tech team in-house is beneficial only when your engineering/software is tightly coupled with the domain. We often overestimate and think that's the case every time -- it really isn't!

Btw if you want to hire such a team, I'm on the engineering end: [e-mail]
