Rather than paying a multisig company. Could i just have 3 remotely located keys myself. Eg safe, pc, phone
Sure, you can, but after setting up your multisig wallet, you should carefully test every aspect of using it, especially how it handles change addresses. Some coordinators
used coordinate relevant private keys or hardware wallets
if you're using any as cosigner might not handle change addresses correctly. That’s why I strongly recommend testing your chosen scheme
hope it is 2-of-3 on testnet before doing anything with real funds on main net.
I think I remember when one brand called mixin safe launch an awareness campaign, I really liked the idea although I was still a beginner when I saw this and since then I have always wondered how successful the project went. I think it's something similar to what op is saying though I can't really place or pin point how the set up was run but I think it required more than one user to set it up which was kind of a loop hole for me although it's good for family set up Incase the owner is not sure of himself in terms of coin.
