It is impossible to decorate the site by yourself, because it involves many props, such as trusses.

You can search the wedding process online. Ask a lively and eloquent friend to be the master of ceremonies. To put it simply, the master of ceremonies will say some warm-up words at the beginning, the couple will appear, exchange rings, kiss the wedding, offer tea to both parents (optional), and leave to salute. This is the easiest way to do it yourself.

If it is simple and meaningful, you can add some interesting links in the middle, and you can give the bride something she has always liked to add some meaning to it.

I hope I can help you. However, once in a lifetime, you can choose a slightly cheaper one and decorate the venue to get the effect.
