How to make a t.v. commercial voice?

Audacity 2.0.6 on a windows 7x64 laptop. Hi, I’m making a commercial for a conference and wanted to know how to make a cool commercial voice. I guess I’m looking for a deep resonant announcer voice. The example that I seen had a deep voice with a little echo that was hardly noticable.

First you need a person with a deep resonant announcer voice.
Do you have that? It is not possible without.
