The quickest way is to use liquid but it's also the most expensive.
Given your unique circumstances I'd probably use a few bags of Dichlor to begin with coupled with bleach additions. You can use the 'effects of adding chems' section at the bottom of the Pool Calc to determine how much to use. Shoot for about 20 ppm CYA. I'd then buy a couple of floaters filled with Trichlor and use them when you have to go back to work. I'd run them wide open. That's not what we normally recommend, but the floaters will keep some FC in the water and will keep you from losing much ground each day. By the next weekend you'll probably be at 30 to 40 ppm CYA and you can adjust your shock level to compensate. Once you get to about 40 ppm CYA you don't want it any higher than that until you've finished shocking.
