Hey Jonathan,
As it was mentioned, there are a few varieties that you can't get unless you happen to have a hop contract with the owner of that trademarked hop.
I think the only one you listed that is not available is the Amarillo.
I would recommend a few things:
1. Try several more varieties. Not all hops grow well in the same conditions. I originally planted 10 plots with 9 varieties. 4 years later, I'm pulling out the poor performers and have enough rhizomes from the good ones to replace them. I'll be down to 5 varieties eventually.
2. Ask around in your local area (where are you located?) at homebrew clubs, or local homebrew stores, if they are available. Hops are weeds, and within a year, are producing so many rhizomes that you can't give them away. Most growers are happy to share.
3. Or, buy from the closest online store to you, physically. This might not make much difference, but the viability is likely higher if they do not have to be shipped across the country.
I have only bought rhizomes (from Norther Brewer, originally) not plants, but they are vigorous growers, and are amazingly resilient. Buying an established plant likely will speed up the process a little, but the extra cost is not worth it.
The higher they grow, the happier they are. The first year, they might only go up 8' anyway, so you don't need to invest much in trellissing, or can use them vertical then horizontal. I have a friend who just lets them grow on his 4 ' high fence and they flower out nicely, but maybe not maximally.
