Yeah, that works; my dear, they're the ones who'll be getting this bitcoin in exchange for fiat.

I’d only use this service if I didn’t have any fiat to spend

That's why I need to set aside some fiat because I don't trust these services and I still get paid in fiat; soon I'll be receiving in ₿ and I'll have someone to pay fiat for me in exchange for my bitcoin. Since getting paid in bitcoin is further off, I'm working on finding someone close by to broker my bitcoin or even use my fiat payment to do this bitcoin intermediation.
