I mean, there are specific recipes for getting different kinds of monsters, but Mike has none of the stuff needed (well... he has some weak demonic essence, Imp Claws, and soul gems to get some demons for a Pseudospace, but other than that, nothing really). 

Yea, your DM is a troll, putting in Items into the auction that are somewhat pointless (not completely, just somewhat) XD (speaking of which, I am going to edit that list soon enough as you guys are starting to get past the weak F Rank stuff and are getting onto E Rank stuff now). Although money is sort of abysmal right now XD
