I believe that entrepreneurs should build their own financial projections themselves. Getting an accountant to deal with it and washing your hands is just not good enough. Entrepreneurs should take the time to understand financial planning in relation to their start-up. It's actually quite easy. Entrepreneurs will have a greater understanding of their business model and be able to formulate a better business strategy.
Here is a slidecast tutorial that introduces how to do financial projections for entrepreneurs.
