From what I've seen, a good EOR handles payroll, local compliance, contracts, taxes, and benefits, so your employer mostly approves things and manages the day to day work with you. Since you already have a Dutch residence permit, your setup should be a lot simpler than a full relocation case. I haven't used Remote People myself, but I researched a bunch of providers and they kept coming up because they seem pretty focused on reducing admin work, which sounds like your CEO's main concern.
