I have been in this from the start. First I built at least one one corporation for everything used in the space shuttle program. They all went broke except for one and it made a little money for a while but I think it is gone now. I built three shuttles in which I still have.
The problem is now I own two space stations in which either I can rent out or use myself. I have never sold anything from a space station although I might if I start using one of them.
My problem is that getting the thing loaded and pointed in the right direction has become a problem in itself. I should spend more time and two or three minutes each month to find out how I get my shuttles loaded and to the space station. Another problem I have found is that a space station will only hold a few items so you have to keep a couple of shuttles moving back and forth to reload your space station if you do find a buyer.
I think I will find buyers for my goods since I have a pretty large amount of plutonium to sell. But with all the work involved i am just sitting on mine.
I don't know if this helps are not but I am sure it will work for some and others will find it to agravating to accomplish much.
