How the hell getting a 10 week coporate finance (M&A) internship in the city

Hi guys, I'm eagerly looking for an opportunity to get a corporate finance (M&A) internship in the city of London, while knowing I'm far away of a top profile. Here it comes - I'm German: -> 2 BIG 4 Internships (Audit, Financial Accounting & FInancial Services) -> 2 DAX30 internships in Management Accounting and Corporate Finance (M&A) -> Non-target 1.4 (Top 2%) -> Semester abroad at the Warwick Business School with 48 CATS and 82% in avg

I also have the limitation that I only have 10 week time frame between End of Feb to the beggining of may 2017.I know it is not enough for the first line but at which banks do I have a realistic chance and should I focus on? I would be very glad about specific names :)

Best regards
