Startup cost: $100 - $1.5k

Low-end estimate includes basic essentials like a reliable internet connection, a computer or smartphone, and a free or low-cost subscription to a user interview platform. This budget assumes using free tools for scheduling and communication, such as Google Calendar and Zoom. High-end estimate covers a more professional setup, including a high-quality microphone and webcam for better video interviews, a premium subscription to a user interview platform, paid scheduling tools like Calendly, and initial advertising costs to attract participants. It also accounts for potential software subscriptions for data analysis and storage, as well as a budget for professional branding or website development. Hidden costs might include transaction fees from payment processors or unexpected software upgrades. While some claim it's low-cost, expenses can increase with additional tools and marketing efforts. For someone serious about this side hustle, budgeting for both essential and optional tools is crucial.
