It is suggested to start a company first, but you should have your own version room, which can be produced in small batches, and you can make your own version.
Be a good brand. If you want to build a factory, you can rebuild it with sufficient funds and start outsourcing the processing plant.
What do you think of the fund? Using others to buy stocks can reduce your risk, but it will also reduce your interests. What about the loan? You just have to pay interest. But if you lose money, the risk will be great.
It depends on your own ideas.
