I like Clipious with Invidious

Real-debrid is worth paying for imo

Paying for a Nextcloud provider would likely solve most of your issues. You can run a lot of services within nextcloud itself using addons.

For video streaming I use kodi+seren+real-debrid. This doesn’t provide local copies, but I don’t really need any. It’s not hard to set up.

I would assume tax write off if its associated with a business.
