Not to suggest a completely ghetto setup, but hear me out
~$30 for a bag of Great Western, $50.33 for 55# of Marris otter. No minimums.
Mash tun, sparge vessel, and boiler--buy three of these from this guy http://eugene.craigslist.org/for/1958367055.html
they are $175 and are in perfect condition. he can convert them to brew pots for $100-$150 each, or you can get a $18 step drill bit and do it yourself. have someone cut the lids off though. his email is firstname.lastname@example.org
and he's about an hour or so away from Portland.
fermenters, either inductor style conicals from http://www.tank-depot.com/productdetails.aspx?part=TN1923IN
(that's the 15 gallon version i use), stainless tanks like the ones above, or there is a guy on http://eugene.craigslist.com
that sells unused (but technically used) HDPE #2 barrels, 55 gallon, for $25. I can't find his ad right now, but they are awesome.
water and sewer in Portland are just gonna be murder. i'd run at least a year long utility cost vs. renting some place east of portland (gresham maybe?).
a march pump, while undersized, won't be in your critical path. save some money and get the $150 model we all use.
electric could be a hell of a lot less expensive with a 1bbl like i'm talking about, but you're gonna need at least 50 amps, and preferably two 50 amp circuits. two 100 amp circuits would be even better. or, propane/natural gas. if you use propane, i'd suggest talking to Ted from Brewers Union Local 180
. he has a neat propane setup, and i'm sure he'll talk your ear off
Also, he uses plastic kegs which are very, very nice. ask him about the pluses and minuses of that.
anecdotally, when it comes to insulating your fermentation chamber, a few friends of mine in the DIY construction business say it is frequently cheaper to get a dedicated insulation company to do the work for you then to buy and do it yourself. economies of scale, apparently. anyway, another thing to do a little research on.
and finally the hard part--marketing! sorry, can't help you there
lots of festivals and whatnot would probably be a less expensive, but labor intensive way to get started. i'm sure there are things i've forgotten, as i am enjoying a wee heavy at this precise moment
oh, and i haven't thought about this very much--why do you ask?
