Interesting.
Did you do any sort of divinations or readings to see if you were being blocked somehow?
Did you get any acknowledgement from Bune when you conjured him?
In my experience, Bune works by changing your life, so I'm not sure if expecting the money to come from what you've been doing all this time is the right method. That being said I am not an expert with Bune so don't take my word for gospel.
It's true that Bune doesn't work to your timeline, but I have not known him to be a slacker, and usually 6 weeks is enough to see some sign of change. That being said, what I would recommend is doing a divination, if it's all clear, reconjure Bune and ask for an acknowledgement or update, maybe make an offering, and then just try and foget about it, and don't let your every thought revolve around "oh my god am I gonna get results now? how about now? how about now?" etc. Just let it be for a while and don't think too much of it.
If you really did confer with Bune and receive acknowledgement, your results will come. Don't overthink it.
