Basic book keeping/ Data Entry

Hi, I am looking for someone to help out with Basic Bookkeeping type work. It is very easy, but I am too busy with other projects so I am needing some help. It is basically preparing an Excel spreadsheet summary of income and expenses, and you need to be able to identify what was actually income/expense in the Financial Year e.g. 1 July 2009-30 June 2010. There are a few invoices/receipts/paperwork to look through, and apply to the correct columns, so you would need to understand a very little bit about Accounting, but it is often very simple principles and I will help you with it too.
