Business: You have to see what orders your target accepts. Government? Unit? Business is hard to say. If it is a new company, it is best to have some background and relationships, so that you can take orders faster. If you work in the government, it is necessary to make friends with some people, or whether there are people related to the government in the enterprise. If it doesn't matter at all, it will be more difficult to do it, but it can also be positioned as focusing on garden construction, and taking orders from people who are related but can't do garden construction is equivalent to outsourcing. If you do this well, you can set up your own business.
Because I don't understand the relationship between your enterprises, it's better to have a relationship. If not, just be a construction team. As long as the quality is guaranteed, business will come up slowly ~ ~ ~
