Offer’s name

I sell a course that teaches screenwriters (including new and aspiring) to write a professional pilot episode.
I wanted to use this title for the offer:
“Write a pilot episode that sells”
BUT – since I can’t promise they’ll actually sell their pilot I don’t feel 100% good with using this title.
Is it unethical, or just not nice to call it like that?
(The course is amazing, I have great testimonials)
Thank you
