Yup, so while those people technically volunteer, I wouldn't be so sure that they're volunteering out of their love for the motherland.
Still, I reckon the order of motivation goes: Patriots who fight for the cause > Well-paid volunteers > Conscripts. So you've got that right. Unfortunately, I doubt Ukraine can offer any contractors nearly as much as Russia does.
I do hope there's peace soon, but that's still entirely up to Putin and literally nobody else. I'm pretty sure Ukrainians would be ready to accept a white peace immediately at this point, without even regaining Crimea or anything, but Putin needs to have territorial gains beyond that.
