How to get a loan (in uk) to start as self employed?

I`m 24 years old. i`ve been living in uk for 7 months (i`m from netherlands). i really wanna register as self employed entertainer and event speaker, but i will need 70 000 sterling pounds to get started. the thing is that after graduating university, i have been using my time to educate myself as entertainer and speaker, meanwhile working on and off different unrelated jobs. i have finished my business and marketing plan. where / how it would be possible in uk to get such a big loan, if all i have is my business plan and few testimonials. i am not a homeowner. plus, i`m a foreigner. what else should i keep in mind? thank you all
Answer
£70,000 is a huge sum to expect any financial institution to lend you, if you have no collateral.maybe you could approach a bank but i dont fancy your chances.
