Choose by situation, not by title. An agency is a monthly subscription for steady work. A freelancer is a per-hour bet on one person. A flat-rate rescue is a single locked price for a fixed outcome in 48 hours — built for the nights when the site is down, hacked, or bleeding revenue. Here is the comparison that decides.

Freelancer

Flat-rate rescue

Fit per situation, honestly scored. No row is marketing: each is the answer an owner gets when they call the right tool for the right month.
