So I am nearly broke now. I ran Amdapor Keep over 100x by now. The repair costs for just this week have been over 60.000.

I do not want to Craft. I do not want to gather some silly materials or go fishing - thats not my thing. It is boring imo. I do not want to level another job to 50 just for the sake to gather Gil,
You're complaining because, while playing at absolute breakneck pace and deliberately ignoring gathering and crafting and farming, it's difficult to make money?

Eesh, just dedicate 2% of the time you've spent in a single dungeon to making gil and you'll be fine. >_>
