I want to start an advertising design company. What should I do?

I have several friends or classmates who have started their own advertising companies. Now some of them earn hundreds of thousands of dollars a year, and some of them are struggling to support them. Based on their successful experience, I would like to offer some suggestions: \xd\1. They all grew up small and lacked funds and experience at first. It is suggested to register a studio or a service department first, which can save a lot of expenses and troubles, and you can re-register a company when you have a certain amount of business. \xd\2. Site selection is also very important. It is not necessary to be in downtown areas, but it is also a good choice near some decorative cities and enterprises. Of course, if you have regular business dealings with some large units, it will be much easier to choose a site. A friend of mine opened on the edge of a large furniture market and did it very successfully. \xd\3. It's not enough to have a few computers. If the economy permits, there must be at least one of them, such that the things you go out can compete with others in price. Other small companies without equipment will also bring their work to you for processing. \xd\4. Just to ensure the business volume, it is not enough to rely on door-to-door business. There must be several regular customers outside, and it is best to try to win over the planning departments of several enterprises and build a relationship with government departments, so that their annual fixed business volume is enough for you to survive, and find a few salesmen outside to do some piecemeal business. \xd\ In fact, personally, I think the fourth item is the most important. My successful friends have a fixed customer base without exception, so that your business can grow gradually. However, there are many debts in doing this business, depending on how you operate it. You should also be mentally prepared for this.
