Thank you for the advice - these all seem like good ideas. Multiple approaches is what I was thinking - I was going to find out what's out there, and start with the ones that seem the most likely to work and don't conflict with each other or add up to be too costly (for example, you can only do so many time-consuming things concurrently).

I have a specific person in mind, and am intentionally being vague about whether it's me or someone else and who. I know it's not very polite to ask for help with a problem without saying what the problem is, and I'm sorry for doing that. I was iffy about posting at all for privacy reasons, but I knew that good advice on this would be really valuable, so the best I could come up with was posting but giving minimal information.
