Marketplaces offer quick discovery, global reach, and flexible engagement models, ideal for experimenting and scaling up or down. Agencies reduce hiring friction through pre-vetted candidates, standardized contracts, and backup coverage when life happens. Consider your appetite for management, onboarding effort, and continuity needs. A blended approach often works: source a generalist via an agency, then supplement with specialized freelancers when workload spikes.
Describe concrete outcomes, daily tools, expected response times, and example scenarios. Include an inbox sample, a messy calendar screenshot, or a travel constraint puzzle. Candidates who ask clarifying questions and propose improvements demonstrate ownership. Signal your values—privacy, initiative, kindness, speed—so people self-select. Add a hidden instruction to test attention to detail, and request a short Loom or written outline of their approach.
Structure a paid pilot mirroring real complexity: calendar cleanup with constraints, inbox categorization using labels, or vendor research with comparison criteria. Define timing, communication checkpoints, and acceptance tests. Observe notes, assumptions, and escalations. Evaluate not just results, but process clarity, resilience under ambiguity, and collaboration tone. A strong candidate improves your brief, documents learnings, and requests feedback before expanding responsibility thoughtfully.
