I'm interested in how you get on with this as this is something I would like to do too, although it would be a few years away yet. I know nothing about larger scale brewing and would have exactly the same questions you have around controlling fermentation temperatures, so keeping an interested eye on responses and any other challenges you face.
For what it's worth, my master plan was to speak to some of the local independent pubs about whether they had unused space in which a micro brewery could be set up. They provide the space, I provide the equipment and we'd come up with a plan about how best to sell the beer. I think that could be done in a way that didn't mean you had the pressures of needing to produce vast quantities and becoming a chore. I think the licensing and planning aspects are easier if you're part of a pub. Alternative is to have the pub fund the equipment etc and just pay you a nominal wage or profit-share on the beer.
