MIM/MSc Finance Pre-experience coming from a non-target uni

Hello everyone,

I'm in my last year of university, finishing a degree in business administration at a non-target university in Spain. I have two years of experience working in the financial area of a healthcare company, and I'm now doing an Erasmus this academic year. I'm having a hard time trying to get an internship in IB/PE or consulting in general, mainly because where I live there are not a lot of this kind of companies. 

Some context:

Not a good grade in general, around 7.5/10, and I haven't taken the GMAT yet (am I late?) but I think I could do it in December and get around a 650. I also have the Cambridge Advance English (C1), so English's not a problem (and I'm willing to learn French/German or both). 

With this in mind, I was thinking to do a MIM or a MScFinance in a top-tier university in Europe in order to gain experience, get out of Spain, and enter in IB or PE (maybe consulting also, but long-term I'm interested in PE/asset management). Do you think that this is a good idea? I could get accepted into a top university? I was thinking of:

If my GMAT is bad or if I don't have time to do it:

MACFin in HSG --> Pros: Cheaper Cons: I don't speak German and barely any French. 

MSc Finance in ESCP --> Pros: I could do half of the program in London. Cons: Expensive

Warwick --> Pros: It's in London. Cons: Expensive 

If I have a good GMAT score (I would apply with a 650 just to try):

MIM in HEC, Msc Finance in LBS or LSE, RSM (I'm already late; it would be next year), MSFinance Stockholm University, or MSc Banking and Finance in HSG. 

What would you recommend me? Any other options? 

Thank you everyone in advance,
