I'm considering a sponsor-based monetization model for my website (ie, a single sponsor is featured weekly on the homepage). Does anyone know of a good way to locate potential sponsors?

To find potential sponsors for your website, consider using LinkedIn. You can search for companies in your niche, see if they have a history of sponsoring websites or events, and reach out to relevant decision makers directly through the platform. It's also a good idea to build a strong profile and establish a professional network on LinkedIn, as this can increase your credibility and make it easier to connect with potential sponsors.
