If I were you.. I'd just toss out a 8 or so clones in june.. they won't get ridiculously large and feed em good before you go fishing..the September rains will pick up the slack while you are gone.
I don't know who the guy is you're speaking of, or the seed bank, breeder etc... but you bought the beans Monday and he said he send out Tuesday and you sent 3 emails in the 4 days since? Do I have that correct?
