Looking for small motors for electric longboard

[MikeLemon\]

Hello,

So I've been looking for quite some time for an sensored brushless motor for a dual drive setup and only came out with one good option which is that:
http://diyelectricskateboard.com/diy-electric-skateboard-kits-parts/electric-skateboard-motor-5055/

Now I'm looking for different other options for those specs:
outrunner
RPM:190KV-280KV
Power:1000W-2500W
max voltage:6S-10S
motor diameter:42mm-63mm(the smaller the better)
motor lenth(Not including the shaft (Very critical)):55mm or less
price:70$ and less
sensored
8mm shaft(Better with keyway but will try to get along without)

If anyone came across such a motor I'd love to get a link to where you can get one thanks.
