Student finance certificate form

I'm applying to student finance via post (I know pretty late, I applied to uni late and was having issues with applying for loans online..) and I need a counter signer for the birth certificate form since my passport hasn't been valid for ten years now.
Thing is, I'm 20 and I finished a college foundation course last July, since then I have been on Job seekers to get by through the last year. All my old tutors at college are away for the summer and I only have one other option which is to get a job advisor at Ingeus to sign the form for me (hopefully if he has a valid passport). However I've only known him for a few months with only being sent to ingeus this year. Would he still be a valid co-signer? I honestly don't have anyone else to sign this.
