Can a virtual assistant actually handle contractor coordination on an active job

Here is the bottleneck for anyone running renovation work while investing on the side. Six trades, none of them answering the phone at the same time, and evenings spent texting people to confirm what they already said they would do. The usual suggestion is a VA for this. The instinct against it is that the hard part of scheduling is not the calls. A plumber saying "Tuesday" means Tuesday or Thursday, and the only way to know which is how he says it. That is difficult to hand to someone who has never stood on a job site. That instinct might be wrong, though. Has anyone in the room actually made it work? The question is about live trade coordination on an active job rather than lead gen or data entry.
