It is estimated that small business need a minimum of 2,500 euro for production and for large business it is estimated that you need to have at least 100,000 euro. However you need to remember that everything is a risk. There is no guarantee for success. You can fail with 1,000,000 euro put in your business and succeed with only 2,500. It all depends.
In fact with 2,500 euro for start you can open small business like beauty salon or barber shop. With 5,000 euro you can open boutique wardrobe for children or for adults. If you have more than 10,000 euro and you are ready to work physical you need to think about raising orange plant. If you have 20,000 to 50,000 euro you can open transport firm, for example you can buy vans and transport passengers. If you have at least 100,000 euro you may think of opening mini-factory.
However you need to keep in mind that it doesn’t matter how much money you invest, but in what you invest. Because as we said everything is on risk and there is nothing certain. Explore what the people need and be creative, we are sure that you are going to succeed. Good luck!
