Do I have a decent shot of getting an entry level role?

Hey guys, so I have nobody to turn to to get an idea of where I'd end up so thought I'd ask here. I'll try to make it short as possible. I graduated from Purdue in 2011 with an electrical engineering degree, GPA around 2.5-2.7. I had no experience, no network, etc. I somehow managed to land a job in a power engineering consulting firm despite that, and have been there for five years. At the time, I was desperate for any job since I had six figure student loans. I now have my professional engineering license, btw.

Year 1 - Terrible - I was struggling a lot with the software we use (not programming software), and was reporting to the vice president, two senior managers, and my boss. Small company, but they paid me well (~60k). Incredible amount of stress. I was pretty much the only entry level engineer in the company, it was very small, almost like a startup. Year 2 - Company was falling apart but I managed to get staffed on a major oil & gas refinery client. This refinery is filled with thousands of contractors, and the central building has all the bigshot managers and finance department. This is where I was put, SOLO. I was basically in charge of pursuing new work and representing our company there. There were many other companies that did electrical work there already and they were my competition. I have been learning how to deal with people on my own and with my boss's help. Years 3-5 - I have been managing myself (no boss at the client office), dealing with many different clients/companies in the refinery, writing proposals, writing technical reports, attending meetings, taking care of invoices, navigating the workplace politics, etc. Recently we got into capital design projects and I'm the manager for that too. When I say manager, I mean that I am a liason between the refinery and my company, and I manage the workflow between. I have performed work for major engineering procurement companies as a subcontractor, run meetings, and have been dealing with people at the highest level of the organization for a while now. My total compensation at this point is $96k, will hit $100k next year. Usually work 30-40 hours a week but I hate the work, and the long (45 minute one way) commute.

Given all of this experience, I have stagnated and want to move into the business world. I have no finance experience. More specifically, I know I won't have a shot at investment banking, but I feel that I may have a shot at equity research. It seems like something I would be interested in, and I plan to take the CFA level one to start. I plan to network and learn as much as I can about the industry for the next year. I don't have the credentials for an MBA, or the time/money (still have $100k student loans). I am 29 this year.

Realistically, do you guys think I would have a shot? Would my salary be low if I did get in? Would I have to intern first?

Thanks!
