Hong Kong “off the shelf companies” are readily available, the main benefit is speed. With little notice you can have your company in 2-3 working days. The downside is that you use the name that came with the company. If you want to change the name you can but it takes two weeks, which in the first instance defeats the object of the exercise.
A new fresh company using your own name (subject to search) takes 10 working days to process.
If your next stop is the bank to open an account, remember an appointment is required. This can be as much as three weeks in advance depending on the bank.
