An entrepreneur is any individual or private concern engaged in business for the purpose of making a profit. Practically all business concerns outside of government enterprises are some sort of entrepreneurship. Entrepreneurs normally invest assets (capital) into their business enterprise with the expectation of profit; but are not guaranteed a profit. Hawking is actually a distantly related form of entrepreneurship which typically involves agressive, high pressure sales techniques and selling on street corners or door-to-door. It typically involves sales of products that are basic or commonplace, like food, cloting items and paintings or books, which a consumer may or may not seek out to purchase. The term originates from the Middle English word for peddler, perhaps borrowed from the Middle Low German. The traditional illustration of a hawker is the "snake oil salesman" who uses histrionics and high pressure to make sales.
