I think the problem lies w/in....
people not wanting to give $2000 a piece to someone who promises to get them motors....
people who actually talk about getting an SR, then actually have the money to do it....(90%)
thats why most places do bring in 10 or more motors, then sell them right away....its not like "well im going to get 10 people together so we get a deal....."...nope dont work like that...unless maybe they were all being shipped to the same location, then you might get some discount off shipping....
If you called up heavythrottle(just for example) today, and asked them to send you 10 motors, they might give you $50 off a motor. and thats saying if they are all going to the same place...
If you had 10 people that wanted them, then the only way your going to save, or make money is to go to japan, pick out the motors, and pay someone to ship them to you, get a truck, go to the dock, pick the motors up off the truck, then drive them to each of the 10 people
there is a reason they are sold by businesses....Im sure if you get 10 people together on your own, who have yet to talk to Midnight Motorsports, and gave their info to daunttless he might hook you up w/ a free downpipe or something for your referal

....and thats if your lucky.
