@bodhipaine Make a list of what you rely on today from the big five, and then figure out the one which will be the easiest and cheapest thing to tackle. Come back to the others as you have time/energy/money.
In the meantime research alternatives on the list. Take a look at lists like https://prism-break.org/en/all and https://github.com/anitwek/alternatives-to-us and others.
