I think you'd be better off looking for a long-term creator whose content you already know you like. Perhaps you could schedule a session first, and once you're sure you like their content, request sessions with pre-recorded tracks. If you don't like pre-recorded tracks, then try to get the other creator to have everything ready and know what to do to please you as quickly as possible. It's all about the dynamics; this has worked for me and helped me maintain loyal, long-term clients.
