There's not really much to say, same as state corps, just keep profit sharing low and try to find locations of low tax, since you'll be getting hit with an automatic 40% taxation (country resources used).
Other than that, use some trade strategies that may actually net you some cash. The default 10 under market does not yield a reliable product.
Personally, I'd junk the 130,160,180 routine people love. Cheapest you can get is good enough, 100Q.
