Eastern Diamondback and Mangrove in Michigan

I have a 2012 female eastern diamondback rattler and a 2011 (I think) mangrove snake. I paid $85 for the eastern and $50 for the mangrove and I'd like to get my money back. The eastern was kind of a pain in the ass to get to eat at first, but is now on frozen/thawed pinky mice and the mangrove is somewhat picky on lizards, but I've have good luck with frozen thawed golden geckos and has eaten a rat pinky or two. I can't ship, but I can meet at one of the Michigan shows if needed. As far as trades go, I'm mainly looking for younger male retics (mainly sunfires and lavender albino tiger), but I try to keep an open mind.
