About references for charter application

I m working in a very small investment company which has only one colleague and my boss. ( total 3 person included me) , my job duties include meeting with investment banker and identify any investment opportunities. my question is if the investment bankers ( they are not employed by my boss) can be my references? I cant find the third people to be my reference in my office, thanks for help.

Should be no problem.
