Yeah, just 3. Not difficult for somebody who knows what they're doing. And also not too difficult if they don't as long as they're able to follow the logic of the spoke pattern (heads on the correct sides of the flange for the spoke direction and laced properly). If the spokes are replaced one at a time and the wheel is roughly trued each time then it won't go too far out and final truing won't be a big job.
