Stuck career/grades wise?

[Rebecca]

Hey guys, so basically Im really stuck with a career at the moment, im 19, when I left school i trained as a hairdresser but I hate it, I gave up my salon job as i want a more intellectual career, Ideally something marketing/finance/business based.
I got 3 good GCSE's, C's in english and maths and a B in biology. I'd love to go to university to study business or finance, but I don't have A-levels and would now have to pay for A-level courses due to my age
I have a good CV, i've worked ever since school and have experience in customer service, promoting, social media, food, retail, barwork, assisting with management and obviously hairdressing.
I just really want to better myself but don't know how...sorry if ive rambled on abit, any help would be greatly appreciated, thankyou in advance xxx
