There are two local establishments that advertise 'giclee' printing (sorry) but both use old equipment: Epson 4000, 7500, 7600, 9600s (nothing more recent) and offer very limited paper selections. Neither seems to place much emphasis on customer-oriented archival printing.

Welcome to the "real world". Don't mean to come down on you, but I've got almost 20 years in desktop publishing (small scale), and the sad fact is, anything digital or with computers the second you venture into any commercial or business applications, it's almost like all the rules turn around on you.
First off, I notice nobody here is mentioning a business plan. Your reality is this - you have three years, maybe four at most, to recover your money before everyone complains that your printing is "obsolete". Your own statement above shows that.
What I mean is this - if you spend say $200,000 on hardware and software (just a figure made up for sake of argument), you had better completely recover all that investment before you have to go out and update everything.
So what I am saying is this - aside form all your "regular" bills, such as lighting, heat, taxes - maybe even payroll (like paying yourself), all your gear will be worthless inside 4 years. People always seem to want to go to the guy who has the newest or latest.
Your second issue is despite being a "fine art printer" and advertising yourself as such, it's is amazing how many people will complain they can get better form Wal-Mart or their twelve year old's inkjet. People act totally different than they say when it comes to money.
Last - have fun with colour calibration. The number of people who have no idea how to properly colour calibrate their monitor, scanner and even their printer is astounding. The vast majority of your customers will NOT be reading the LL forums for advice on these subjects, they will just assume they know better, so when they bring something into you to be printed, and they have no concept of how natural VS artifical light affects how a print looks, be prepared to do a lot of educating.
Sorry to dump on you, but I think regardless of what business anyone plans to get into, you should have somebody sit down and give you a two hour talk on all the things that can go wrong, before you learn them for yourself the hard way. You'll save a lot of money in the long run if you do.
otherwise, good luck!
