Vickie Sullivan, who runs a Speaker's Bureau, suggests using a postcard for making first
contact with potential clients. The card should read "...regarding your
meeting in [place] on [date]....[your name] with no travel expenses." then put a
link on there for a video or more information. After
sending the postcard, follow up with a call (for a reminder) and email (to send a clickable link to your website). She suggests a postcard because phone calls and emails tend to get lost when making first contact.
