even 3K willbe enough they will see you can save money and manage it good , they mite give it to you then or try and different bank. i got my first loan of 18K with a job that wasnt permanent or fulltime ( i was fulltime causual) and iin that job i was affected by weather aswell, also they said i didnt earn enough to take out the loan but they lady said il write down here on this form, that she spoke with my boss and work will be picking up soon and you will have a constant cash flow in the next 8 weeks. and i got approved. too easy, she looked after me though.
