So I'm in the starter ship - I buy some goods and sell them at the best profit I can find and make about 10Cr..... thinking I did pretty good I stop by a shipyard to see how many runs I need to buy a ship and they are obscenely expensive.... How can I carry more than 4 items so I can make some money to buy a bigger ship?
Wow, I don't know what went wrong on your end.
I started a fresh game on Sunday. Basic Sidey, 1000 Cr. start capital.
I found I started in an agricultural system, and in the bulletin board I found a mission to bring 2 tons of scrap to a neighboring system for almost 4k. I bought 2 additional tons of food, because thats what agricultural exports and all other buy.
I flew to the neighboring system, found it was a refinery, and delivered my mission. Got 4k. I bought some waste, because thats what I could sell back at the agricultural system, and explored the rest of the refinery system, as I had no map data at all. Additionally there was a mission bringing intel back to the system I came from.
While doing so, I got interdicted and attacked by a Competent NPC Viper. Okay, I must admit I had some fighting experience from the Alpha and Beta stages. I killed the Viper in my stock sidey with 53% hull left and almost all systems between 80 and 95 percent, but gained a bounty voucher of over 8k Cr.
I explored the rest, flew to the agricultural system again, sold the scrap, redeemed the bounty voucher.
I am now at 13k Credits after all repairs, and I have almost 4k worth of exploration data I will be able to sell some lightyears away.
And that was about 2h game time. So 2h flying, making 13x your start capital isn't that bad.
So my advise: Look at the bulletin board and run missions if you can. Look what additional cargo you can haul along your missions.
If you are attacked and see the guy is wanted, try to go for the bounty too. You will loose your ship one day, but since you do not have that much cargo to loose, it's not that much of a problem when in your basic sidey until you made enough for a bigger ship.
Also, if you have the Mercenery edition, you could also sell your 'Freeeagle' for about 40k, but I did not do that on purpose.
