Need Advice on Getting a Fall Intership Last Minute

I am a rising junior currently working at a PWM desk at a BB (I have been working here for the past 2 years) and have been networking internally to apply for their summer analyst program but I feel like only having PWM experience and investment club experience on my resume will not be enough to make the cut and land an interview.

Knowing this, I was seeking a fall internship in PE or IBD and landed one at a small Private Equity Firm that I would work at during the semester. Unfortunately, the offer was cut short last minute due to factors beyond my control.

Now I am scrambling to find something to do in the fall and have on my resume that I can talk about during recruitment. I have begun cold calling and cold emailing Boutique Banks with little success and have no idea where to find Director's contact information. Any advice would be helpful.
