If sows may have been near boars, I keep them 10 weeks to make sure. If they come from a pet home and were the only piggies there, I wouldn't wait as long.
I quarantine everything for at least 2 weeks before putting them up for rehoming to be on the safe side, as sometimes it can take that long for symptoms to show (e.g ringworm).
On the website I have a page for 'new arrivals' that is updated whenever new piggies come in... then they get put on the rehoming page once through quarantine. People can reserve piggies for rehoming once they're through quarantine.
