In order to do this, you'll have to use the Balloon method as mentioned above and that takes an incredibly long amount of time... so!
ZMI'ing using the long and winding route (just to answer your question KerokeroCola and give IxII some insight) is skiller friendly. However your chances of making profit linger throught this process. Many times you'll break even and occasionally lose profit, being a skiller and R.C.'ing is limiting, long and extremely tedious but ballooning laws is sheer profit.
To the right is the ZMI map, look closely and you'll see the skiller friendly path, it's long and windy and you can't miss it!!
