Job Strategy with no Investment Banking Experience

Can someone please advise on what I will need in order to have a shot in getting trained by any VC, JV , hedge fund or Equity firm or any IB company?
I know some of them might be out of the question. I noticed IB courses for like $2,000, Im sure it's worth it. I am 30 yrs old and work in Res. & comm. finance for 10 years and through the years I have gained very strong contacts.

I am trying to look for companies that fund high volume projects like an Oil Refinery project, Or a Casino or even a Wind Mill, just as examples.
I think I've had enough running around trying to look for people who work in these firms to help me fund these deals and and I want to make the move myself and to go to work for a firm that does...

I've heard of these Boutique companies and not exactly sure what they look for in a candidate either.

The more I look into this IB side the more complicated it gets..VC's, JV's,Syndicates Don't know where to start to look for such company..!!

I am having trouble distinguishing the right position and name for this field or firm Involved who Invests or can Lend in such transactions/Projects and what it would take to get in these companies? (For example as a Loan Officer, You originate loans then take the application and let the processor do the verifications and so on..

This is what I am trying to distinguish if such model exists that will allow me to bring deals in,do my due diligence on preliminary materials may be that is missing on a deal and make it complete so the firm can fund it or whatever do a JV or whatever it is..
Just like in a JV project Or Syndications and so on...
This is the biggest question that I have ever faced in my life and the answer can definitely change my life and I hope there is someone here that can help me pick the right route and the right decision.

Thank you kindly,
