Hello, i’m a professor at university and i need help writing 2 excellent letters

Hello, i’m a professor at university and i need help writing 2 excellent letters of recommendations for one of my most out-standing students. I want the 2 letters to vary enough for her to choose which one she prefers i sign off on. I have no time to write one and she needs it for her dental school applications very soon. I have requested she shares with me a copy of all her on-campus and off-campus experience and she shared the document with me. i will be sharing it once a writer is selected.
