What kind of audience do you need to reach? How large is the audience, generally? How long is the speech? What's your topic?
These could be short-term, long-term, or both.

Please list times during the week you could be available for a session. (Sessions run 45 minutes. A typical series of 2-5 sessions could either happen once or twice per week.)
