First time paid for writing!

Yep, I earned a whopping $75 for writing a short speech for a bride to be, to give at her fancy engagement party. She got great feedback, and has recommended my services to very close friends.
Anyone have input on how much they would charge for similar work? I just got an assignment for a maid of honor, because she has no desire to write her own toast for her sister's reception. I am wondering if $75 is still a fair price, even though it may be a little harder to produce.
