Ok -- was asked "how does all this work" re: docking, etc.
I'm using:

...as guidelines.
In this case, the FTY is silhouette 4. So docking fees are 250 credits per 5-day week (which is the SW standard, apparently).
I'm using the fuel and provision costs elements and the maintenance bay access costs from this sheet as well. I may or may not entertain rolls to adjust the pricing, either as a randomizing element to reflect local economy or due to negotiation skills. Note that in the case of Kwenn station, it's controlled by Hutts and is huge. The opportunity to negotiate pricing on basic services is quite limited.
Also note that as Hutts, they are happy to rack up a bill as "credit" -- perhaps with an extortionate interest rate. so if you can't prepay for access to things, they are happy to "put it on your bill"
