Lots of questions--
Not to discourage you but $100,000 is not a lot of money to start a "microbrewery" although others have done it with a lot of sweat equity of course.
How much room is there for brewing equiment and fermenters and grain, refrig, yeast lab and gear?
Will $100k be enough money to buy a big enough system so you are not doing two brews a day?
How are you getting paid for your time? If no salary, can you live on savings for 6-12 months?
Is the place zoned right?
Does it have a good water source and waste-water disposal?
Who pays for the grain, hops and yeast, plus other items like-- Insurance? Workers comp? advertising? Brewing licenses? Permits? Construction required for install?
Do you have any experience brewing on a multi-barrel system?
Do you have 2012-2013 harvest season hops on contract?
How many kegs can you afford to buy, and who cleans them?
You get the idea. Read pro brewer business
books. good luck!
