There may be a reason why no one has posted in the Simple Requests Thread - only 2 posts have been made since you posted in the Simple Requests. Either be patient, or maybe try the GTS? It might be a long shot, but you *may* find the legends on there. Ignore any requests for Lvl 9. and under Reshirams, Zekroms etc, as they're obviously impossible to get. Try changing the searches, especially by country / nation etc and leve. You'll limit who is requesting, and you might weed through a lot of the impossible trades.
I can't help you I'm afraid - sorry.
As this is against the rules, I'm going to lock this thread. Good luck with your hunt though :).
