i think paperwork is either something you like or hate
how did you get on?
i'm currently trying to find some self-employed work doing just this kind of thing. bookkeeping mainly but that would include producing invoices and secretarial things etc if required. Trying to do it without spending loads on advertising so it's not easy!!
I'm a freelance bookkeeper, and I have clients from both ends of the organisational scale - one sends me a seven page colour coded excel spreadsheet with all her income and expenditure and calculations; one sends me a fat A4 envelope with all his receipts and banks statements in a jumbled mess. Domestic paperwork is a different story mind, I'm hopeless at that
