Mike here a few resources that I've found to be helpful.
Your uncle skippy told me to look up Robert Harper, here is his site which has some great info:

Black Pearl's Drymarchon caresheet:

Besides these i've gone through forum after forum and read every post I could find about Drymarchon. Fauna and Bush league breeders club have a good number of posts from what I remember. Unfortunately it seems most Indigo forums are rarely updated.
Also Skiploder was kind enough to send me a powerpoint of his on Drymarchon. I'm sure he'd send it to you or with his permission I'd be happy to forward it to you.
Once you start looking into these guys I don't think you can make it more than a year without taking the plunge yourself.
