Well there is a difference between a bookkeeper and a cpa to do your taxes.
I have a girl come in once a week and do general bookkeeping and office work that I rather not do myself. She does not do my taxes though. I have a tax guy for my taxes that I meet with a few times a year.
Once you start making making enough to live on then you should probably visit a cpa to see how much money they can save you. Usually not very expensive and in my case he always find something I would have missed so I at least break even and usually come out ahead.
