I dont think you correctly understand how multisig works or how you would go about setting it up.
He was right. And with a bit more explanation and research, it's clear to me now that
the method that I built this service is pretty well obsolete when you include multisig.
I had the idea to encrypt BTC private keys with public PGP keys, and provide the simplest escrow possible. In my opionion, this method is
still safe, but not knowing about multisig and running with an idea kinda bit me in the arse here. This is why research is important.
I still believe in the right to a free and safe option for escrow, and would still like to see this vision a reality.
In the meantime, it's been suggested to look into partnering with a third-party trust; I'll look into that.
There would be no harm in offering both 1-of-1 alongside 2-of-3, for those who truly can't wrap their head around multisig, or laymen.
That's all for now, thanks to everyone for their input and direction.
