No need.
Qualifications are not required for signage design. However, installation may involve high-altitude installation, which requires the installation personnel not to have a high-altitude installation operation certificate. There is no qualification, you just need to register an advertising company, in the form of a company. Advertising company, with a registered amount of more than 500,000 yuan, and its business scope includes an agency to publish advertisements. Advertising companies with a value of less than 500,000 yuan do not have this provision. Without this provision, they cannot directly operate outdoor advertising.
It is very troublesome to handle it by yourself. You have to go to the Industrial and Commercial Tax Bank. It is convenient for an agency to spend money, including the capital injection fee of more than 10,000. I also provide my own experience: The way to avoid these troubles is to find an advertising company to cooperate. You are Party A, and the advertising company is Party B. The contract between you is a lease contract, similar to a house lease contract. The cooperation method is that you lease the billboard to the advertising company for a certain number of years and pay it annually. The advertising company will be responsible for future approval and operation. Just collect the rent. Or a cooperative sharing method will also work. It depends on how you talk about it.
