I can't tell if you're serious about "Valve as big enough"

Valve isn't some small indie company. They're not massive in terms of employee size, as they're only in the hundreds, but remember they have some of the biggest gaming tech stacks, such as Steam in itself, but also games like CSGO, which is arguably still one of the biggest fps games. No doubt they run those things solely by themselves without contracting some of the work outside of the company.
