Working as a book-keeper pls help me ?

If you have a degree in accountancy you should be able to do a lot more than you have done, you should be able to a company audit. You say you have done to trial balance, I can do more than that and I do not have a degree in accountancy, have you done control accounts, wages, management accounts profit & loss accounts are you SAGE trained. Sorry but from what you say you do not have enough book keeping experience and you do not have enough confidence to become self employed. Good Luck.
