I attended a friend's wedding in church. I think it depends. If you don't have time, your friends don't have time to help you decorate. This is called wedding company decoration, but you have to buy specific props and other things from them. If you decorate yourself, you will spend less and less energy. After all, this is your first renovation and you don't have much experience. But personally, if you have your own ideas or new tricks, you'd better organize them yourself, which is more meaningful.
