First off welcome to the site! Sounds like you got a nice feeder as well it took one of my BPs a month and a half to eat for me. I personally don't handle my snakes daily just my preference, but I know people that will handle every day. When he hisses at you just continue to pick him up because if he associates hissing with you leaving him alone, he will hiss even more. I know it is scary when you get hissed at but don't be afraid to get bit, it feels like a pinch and worst case is that he might draw some blood.
