Graduating Senior - Need Advice

Hello...im a graduating senior from a state school in va...as of right now i am an Economics major with an International Relations minor. My GPA is 3.2....and as of now im hitting 550-600 GMAT practice tests (taking test in 2 months)...

Experience: Extern - Asset Management (wealth management/financial advising) Intern - State Senator Former Entrepreneur

-> Currently being considered for an undergraduate internship in Venture Captial (First Undergrad they have ever considered)

What are my chances for Investment Banking????????? I applied to over 100 trading firms and got rejected or were offered positions with no pay for 6 months (which i am skeptical of)...My goal is to be like Carl Ichan...i mean technically, he was a Pre-Med Student at Princeton...and dropped out of Med School..became an options broker and bought his first company....then build this empire...i want to do corporate take overs...my options are:

1. Take a full time position with the Asset Management company-> They are courting me hard core lol...30-40k base plus commission...and get my CFP or CFA (Unlike other shops they actually advise people...not just sell product)..
2. Go to grad school and get a MSF or an MBA from my school...it would take 2 years and 16k a year...economically this would be good because i can still live at home or at dorms and learn the finance that i have yet to learn...i dont know nothing about technical finance...i am really good with overall finance and good with economics but i dont think i could put together a pitch book as of yet... *Also if i stay here for2 more years...i would get work experience (hopefully at the VC firm)...and beef up my resume a lil more and just apply for analyst programs when i get my MSF or MBA

What would you do and y?????

Thanks for the help
