Take the wedding you hosted, the wedding you think is good, and your resume, just go to the wedding company and have a look. Most wedding companies will not refuse you.

Then leave your message, and the wedding company will call you when there is a new candidate for you.

I'm talking about a professional wedding ceremony. You can go to several companies and leave your message.

But if you want to work full-time in a wedding company, you should not only be the host, but also do other things.
