What are some career possibilities for someone with absolute pitch (perfect pitch)?

I m struggling at my current job (I work in a warehouse, packing boxes and fixing items so that they can be sent to customers), but am looking to switch careers.) I love music and play the piano, I also have perfect pitch (a rare ability to hear tones and determine what musical key they are in), an example being the bell on the paging system at work, which is in the key of E. Any suggestions on any career paths I can take in the musical field so I can put my perfect pitch to good use is greatly appreciated. Please and thank you.
