Why shouldn’t she rush the process? It’s a mitzvah to get married, and the earlier the better. Rav Avigdor Miller zt”l encouraged girls to get married straight out of high school, at age 17 and 18. He speaks of this in his seforim.
Rav Miller also says that the husband should work and be the king of the home. If she will go work and be the king, and allow her husband to learn, she will need time to prepare.
