The real question is can you do without this job? You are dipping your toes. Once it all starts be sure to seriously think about how things happen on the ground. Don't let yourself be overworked just because finding something else feels unappealing. Honestly it sounds like red flags to me. If they need you to determine what tool to use, then they need to be paying you for those choices since it sounds involved. If they cannot move the start date up, they should wait until you start. I think your boss is probably going to hit you with as much overtime as they can out of incompetence (best case scenario).
