Beyond the usual platforms, explore sites like Toptal (premium freelance gigs), Userlytics (paid usability testing), Etsy’s Printify integration (for custom merch), and Ko-fi (support from fans). Others include Rev (transcription), Test IO (bug testing), TaskRabbit (local tasks), and Merch by Amazon (passive t-shirt sales).
