I want to start up a Business.. what should be my first step to doing so?

Hi lmane,
Thanks for the question. This is one that comes up quite often here at Bplans and because it's a common question we've written an entire section of articles about it. What your first step should be will really depend on what you already know.. I'd recommend reviewing the content in our "How to Start a Business" section of articles for ideas on what your next step should be:

get sufficient knowledge about the venture that catches your fancy. Once you are knowledgeable  about it, understand its dynamics as business venture that is out to make  profit. Then set about collating  costs of its operation, and project modestly as to how much you are likely to be making . Once you have grasped this stage , the first hurdle is over . Bon voyage.
