Check out this thread - all kinds of people using (food grade) agricultural tanks into conical fermenters. I bought one for about $50 and it works great. http://www.homebrewtalk.com/f51/super-simple-15g-plastic-conical-276378/

I don't need those capacities, I'd just buy a Speidel fermenter if I wanted to use food safe plastic.

Have you thought about using a pressure cooker as the base? Those usually have the clamps and an airtight seal in the lid already fitted in, plus they could double as a pressure vessel if you want to counter pressure fill directly from a keg. All you'd have to do to the cooker to get a fermenter is fit an airlock on the lid, and that would be it.
Also, depending on where you live, you might get them cheap (military surplus, industrial kitchen sales, etc.).
If you won't use a pressure cooker, then I'd say getting a huge stock pot and installing a gasket and clamps might be your best bet.
For example, here's a military surplus pressure cooker (pic related):

Anyone ever build a Brutus? I'm tired of nigger-rigging a ladder.
