my plan would be pretty much what my country is trying to do (I hope) and what South Korea has successfully done already: tell everyone to sit on their asses while massively scaling up testing capabilities so that everyone can test every few days. follow up on every positive case, quarantine carrier and all contacts. test everyone (literally) crossing the border, quarantine as above. this allows to open the country back up while waiting for a vaccine in 12-18 months... or however long it takes.
South Korea can test about 10,000 patients a day. Their total population is about 50 million. They've primarily been relying on contact tracing to target their testing, I think.
