My good friend, after flying with you over these last few nights, I would recommend you charge 100k per systems visited. However if the long range scans indicate hostiles on your route I would advise the Trader to change route or up your price to cover insurance payments should you fall to hostile guns.
That said, you are a fine pilot and maybe the hostiles might need to up their insurance rates, if pirates can get insurance. I find most pirates these days seem to use gunboats and above so be careful when engaging. Remember he who runs against a bigger ship lives to fight another day.
