Hi Tricia, I'm not a REVA but your question applies to general business development, I think - so I wanted to direct you to the section on
Virtual Assistant Contracts here at VAF. I'm sure you'll find lots of information and suggestions there that will help answer your question.
There's also a forum on
General Legal Issues where you might find an answer to your question.
And you can also use the SEARCH link in the top-right of the main menu to bring up existing threads specifically related to your question(s).
I hope that helps!
