I did the same thing to figure out how much money it makes...I got Game room x10, Storefront x1, guard room x1, vault x2, office x2,
common room x3, storage x8, kitchen x10, bar x3, lodgings x1, bunks x2, bedroom x3, armory x3, infirmary x1, animal pen x1, battle ring x1, statue x1
Staff was another guess: Scofflaw (game dealers) x12, Guard x 8, Craftsperson x12 (cooks), lackeys x20 (waitpersons), Craftsperson x4 (cashier, other).
My Total GP was +415, but that may be off because I didn't all all the income from every room (don't remember why).
So if the person running is can 'take 10' and get +20, that would be 435 or 43.5gp/day. Subtract 3-4gp for the manager's wage and you get around 40gp/day.
By the Gold Goblin Profitability Chart (pg 24 in the AP) the PC's can earn up to 60gp/week. 40*7=280gp/week - (4 PCs x 60gp)= 40gp/week profit..... Saul isn't a very good business man.
A late reply, but what the hey ...
In this case, mixing the abstract rules from the AP's original writing and the Ultimate Campaign Rules does not work properly. In the original, the total income of the Gold Goblin is unknown.. the PCs only know the share of the profit they get from Saul, and Saul is skimming a good deal of gold before accounting for any of it.
Therefore, to actually use the Ultimate Campaign rules, you would need to determine how the bonuses for various missions affect the UC rules. Probably, they'd give a bonus for 5 days (the presumed work week in UC); I would increase the bonus from what is shown in the missions to make it have more of an effect. You would THEN need to determine how much Saul is skimming, how much is left, and how much gets to the PCs.. probably quite a bit less than the possible 60 gp per week per PC in the original write-up.
This then raises the question.. is it worth the work? I decided it was not worth the effort, for my own use.
