Now, I can do a lot of things with the space, however, as it is dry, has a loading dock, is at least temperature controlled (might be climate controlled as the building has been used for document storage for a decade), and has a dry fire suppression system installed and working.

It's a hub for shipping having the port in Long Beach, etc.

They are free with just the cost of shipping at www.vistaprint.com, and some other sites.

They don't offer all b&W, but they're charging $188.88 ($150.97+$37.91 Ground) for:5000 postcardsColor front / b&w back with matte finishFree email proofsProduction time of 4-6 business daysGround shipping (2-4 days)Locally, you might try  AlphaGraphics for high quality products and services.

I will definitely check them out and see how they compare with shipping charges, etc.  

It has army bases, huge shipping port and lots of economic activity that is strong.

Or is this just the tip of the iceberg and I'm looking to hit something that could sink my ship?

I have used bestonlinecabinets.com for multiple projects great real wood quality and fairly easy assembly and good support as well as direct shipping usually included for a full remodel. 

Heck, just go on a cruise and watch for similar sales 101 techniques used to up sell shore excursions, on-ship "exclusives," or on-shore VIP jewelry retailers (aka retailers the cruise line gets a kickback on).

There are attorneys who make millions just going after mail order businesses just for failing to disclose part of the shipping costs on their orders, every buyer gets a $5 coupon and they get 50% of the settlement of 5 million.
