Bookkeeping for a freelance producer

I'm a freelance producer who has just started to pitch directly for production jobs. I've just registered for VAT, have an accountant and a pile of receipts. I need someone to take this on for me and deliver what my accountant needs. It's not a big job in the scheme of things but one I don't have time to do. I'd prefer someone who lives in London, perhaps North London where I am. Would probably suit someone who can just manage it in their own time rather than a business. References are absolutely essential.
Thanks
