SA Internships for Senior Year

Hello Monkeys,

Fairly late on the whole IB thing and I'm starting to stress out. I've had two Big 4 Accounting Internships in the past and now when I'm applying to IB's, I've realized they want more actual banking experience. So, I've been trying to find internship and co-op opportunities to get some banking experience on my resume, but I've had difficulty finding any. I am currently a Senior in college at a non-target (think Baruch/ Fordham/ UWash) in my last semester before I graduate.

So I have two questions:

1. Are there any shops that frequently hire Spring interns? Or any resources to find out which ones do?

2. Has any bank ever offered a non-traditional route for SA's? Like one where you would complete the SA role in your postgraduate summer as opposed to the summer before your senior year?

I know I sound fairly uneducated about the whole process, and while I may be ignorant, I am aware of how needle-in-the-haystack of the opportunity I'm looking for, is. I think I would be even more uneducated if I didn't explore every possible avenue in order to achieve what I want. Thank you in advance for all your criticism or your help.
