Alright, I can sell the amount you wish you up to 1k for 2k per 100 bandies - but we need to meet somehow.
Otherwise, in New Magincia, find one of IPKUs houses (the one with murrican flag in it), inside there's a vendor named "Smoke Bombs" who sells encha bandies in stacks of 100 for 2550 gold per 100 bandies.
