Advice on hosting fixed slot GOs?

I have been a GOM for a while and have been toying with the idea of hosting a fixed slot GO for BNDs comeback, however, i’m unsure on how much i should have in my bank for it. i know GOs cost a lot of money to run so a fixed slot is no different especially if id have to cover claims for people to get what they want so i don’t wanna shoot myself in the foot by not having enough money to run. does anyone have any advice for hosting fixed slot gos in general?
