One semester to go and I dont know what to do

I am a senior with one semester to go (I graduate in December) at a non-target university. I am a finance major with a cumulative GPA of 3.29 and a major GPA hovering around a 3.5. I have worked my entire way through college and am paying for it on my own without any scholarships/grants (excuse for my poor GPA). I am currently an intern for the summer at a private wealth management firm that focuses on small businesses and individuals. Along with this I had a corporate finance/IT rotational internship with a major energy firm last summer. I am wanting to make my way into either an FLDP program or break off into the PE or IB sector and I am not sure how to go about it. I am leaning toward taking my GMAT and applying to top MSF programs at target universities. But I am really not sure and any advice would be greatly appreciated.
