One thing I've learned in the last couple of months is that you can pretty much use just about any kind of vessel you want for a mash tun, boiling kettle, and a fermenting vessel as long at you have a means of cleaning it and keeping it sanitized well. I have some friends that just started a brewery a year ago and they ferment there ales in plastic conicals, granted they are not that big yet but they seem to be working for them. One of the owners told me he could get a 30bbl plastic conical for $1600, that's damn cheap. Biggest thing is, if your just starting out is pound the pavement and get out there and sell your product, go to brewers dinners, start a facebook page, sponsor some events in your community. There are a lot of ways to get free or practically free advertising out there. As far as your beer is concerned make sure you have some solid regulars in your line up that people really enjoy, once you got that down do the more interesting stuff, oh and make sure you scale your recipes so they are easy to replicate. It looks to me like for now you'll basically be doing homebrew sized batches, you wont have to worry about all of the pumps, hoses, and fittings that the bigger guys have to worry about, when you get bigger you'll really want to go try some stuff out. I've already decided what sorts of fittings and clamps I'd rather have, if I had never used various ones I'd have never known. Oh and make sure you talk to other pro-brewers all of the ones I have talked to so far have been more than willing to dispense advice.
