FIRST: announce impeachment proceedings in the House.
IT ENDS 1 of 2 ways:
1- Trump resigns after being exposed in the House hearings for the mountain of evidence against him, before the vote on the Articles. No formal charges.
WHICH WOULD YOU CHOOSE?
The beauty of that, is it would happen very quickly, 2-3 weeks maximum.
(In a perfect world, he would resign immediately upon finding out the alleged crimes at the formal announcement of impeachment proceedings.) Days, perhaps a week.
