Niko, there are two good drops from BCNM40.. Phalanx (200k) and Erase (300k) ... u can only get one of those at best from a single bcnm. First off, its only a CHANCE that you'll get one, second, if u do, you're askin for 5 people to split 10k worth of stuff while u get 300k... not likely >< .... only way to do this is to either ask friends to help you out and do it purely with your orbs and and give everyone the understanding that they're only helping, not earning money... the other alternative is the same idea, but take on a BCNM party that does the whole "my orb, my loot" deal... but again, requires your orb to be used, and only a chance at erase....
if you ask me, best bet is to save up seals and get a full party of BCNMers or two to go out... with a good success rate (which should be easy) then you'll probably get 50k in 2 out of every 3 battles (sometimes you'll be luckier, sometimes you'll just wanna shoot yourself after gettin nothing in 5 runs ...grr...) meaning that you'd have your erase scroll in 2 or 3 BCNM trips
