By now you should have an idea of which skills are becoming important. The Navigation sets, with the afterburner, MWD and handling are critical. So is hull modifications, namely hull ge vis upgrades (better cargo expanders).The Starship skills you have chosen should meet the goals you have set for the types of delivery ships you wish to use and you should be on your way to a "bigger" Industrial.So what of the rest? Well, now we are going to concentrate on the ability to use trade skills to or utmost advantage. You have probably noticed by now that you are getting socked with a hefty sales tax and broker fees.These can put a dampener on your bottom line, every day, and every trade. You should have trade V by now, if not get on it.At least to level 3, now go get marketing, broker relations, and Accounting. Broker relations and accounting will decrease the fees you pay when you place a buy order for items not yet listed to sell, and the tax (10% per level ) for each and every sale you make (Acct) Why marketing you might ask? Ok I'll tell you, but under the market section. So get it all there first, and sell it together, buy the same way, all at once.
