Share a working link or a short screen recording. Compensation: $50 flat. We evaluate whether the agent sounds natural, captures the right information and hands off cleanly when it cannot answer something. RATE $15 to $25/hr, or per-client rates negotiable: roughly $200 to $275 per new client setup, plus $25 to $40/month per client for ongoing maintenance. CONTRACT TYPE: Part-time, ongoing. Fixed-price per deliverable preferred over hourly. HOURS: Variable, scales with the number of active clients.
