Hello/Advice for UK Graduate

Hi,
I am a graduate from the UK, I have a degree in Physics and a Masters in Laser Physics from two great Universities, one ranked among the top 10 in the country. My Masters was great, it taught me a lot of transferable skills, the kind of "soft" research skills a physicist lacks, but the exact kind that you would need in finance. I currently run my own business, a private tutoring agency and I also work as a private tutor, teaching maths, physics and engineering. I graduated at an awkward time in December 2012 and after leaving University I have worked as a tutor, enjoying some down time. I started to get on to looking for graduate work in September, but up to now I have had no success.

I have a few problems. I have no internships/ previous work experience and a 2:2. There is an explanation, I have dyslexia and I was diagnosed after I completed my masters, so I did not get help at any stage of my education. I believe this had a significant impact on my education, as I have always been hard working and well read at all stages of my education, but I always struggled to finish exams in time, mis-read or misinterpreted questions and performed poorly on extended worded sections. I would have liked to have gotten an internship, but with a 2:2 and no explanation for it, I would never have succeeded.

I am looking for a way forward. I have put a few applications in to some big IBs but I have not had a positive response back from them yet. I am currently working on applying to some hedge funds based in London who are recruiting graduates. I have also been reading books on the area to increase my knowledge of specific technical things and help me prepare for future interviews, but I do already know about the industry and I do stay up to date with current affairs and the economy anyway.

I wanted to know if anyone could give me advice on how to move forward? Especially anyone from the UK already working in finance.
Cheers
