I’m starting a website but I have no idea how I’ll keep it up to date as one person.

This is not the concept but think of the website as being one that tracks celebrities relationship statuses. How can I update and keep up with 1000s of celebrities relationships, and any other info on their profile like age (changing ages) and all that? Any advice on how I can best automate this and/or keep up with it? I’m open to hear free or cheap recommendations(really looking at this more as I start)and the pricier options.

Thank you
