Asking For A Testimonial Letter

Dear Sir,

Your presentation was the highlight of the whole conference! We felt honoured
to be able to do the lightning and sound for you. We felt we were able to
provide a dramatic environment that really enhanced your presence.

Do you agree? If so, would you consider writing us a short letter of
recommendation that we could use when we tell others about our services?

Thank you for considering this. We look forward to serving your needs again.

Sincerely,
