Methods I'd try first: Take out a credit card (might not be approved in time, since you only have 2 business days), sell stuff on Craigslist (more money/longer time to sell), sell stuff at a pawn shop (less money/immediate sale), or try to find some one-off odd job or something similar that pays immediately between now and then.
Less desirable methods: Auto title loan, payday loan, get a friend to front it to you.
Hail-Mary type last-minute methods: Win it gambling.
