You get 60k/hr worth of Sq'rks.
13,000,000 ÷ 60,000 = 216 hrs. Assuming you do what Shoop said and buy the beer glasses while you let the bot run, that's about 9 days to 99, with maybe 5 hours extra of preparing the juices. If you let the bot gather the glasses itself, add another 10 or more hours.
