My question involves name change laws in the State of: Missouri

I posted a question over a week ago about changing my name and that I am representing myself. I petitioned the court, now have a case number and a judge was assigned. But because I petitioned the court myself, I am not sure of the length of time this process is. There isn't a hearing date, probably because in some jurisdictions in Missouri, you do not actually have to go in front of the judge to have your case heard. It is my understanding that the judge will enter the order via mail and after that point publication to the papers will be made and so on, but theoretically speaking, about how long of a process am I looking at?

Thanks for any help!
