I have left employment in 2013 from a local municipality to start my own business. I do government tenders supplying IT equipment and consumables.I was however forced to find alternative income streams due to cash flow problems from getting paid late and slow procurement procedures. I have since created an alternative income and the 2 businesses compliment each other...so back to your question , the competition is not as an important factor as to question weather one is able to do what it takes to succeed and chip away at the ice every day. Good luck
