Building your own team buys you the most control. The people absorb your domain over time, and this context remains in the building. The price comes in the form of slow hiring and fixed overhead: recruiting a strong engineer routinely takes several months, onboarding adds more time, and the cost continues through the quiet quarters.
Full outsourcing implies an external team owns the outcome: the partner staffs the project, the provider manages the process, and they carry the delivery risk. This fits well when the work is a defined project and there which is better laravel or .net a decision maker with time for it. It fails when the requirements change weekly, since an external team is not able to invent your business rules.
Hiring individual contractors falls in the middle: you add engineers but keep responsibility for delivery on your side.

Last: who will maintain it in two years? Work through them with real answers and the appropriate option becomes obvious.
