Both Cakewalk by Bandlab and it's upcoming free replacement, Sonar, have a Prochannel channel strip insert available on each track.
Investigate the Prochannel vocal presets. They are good starting points to quickly get a good idea of the different sounds that you can achieve from your vocal. You may find a preset that sounds almost perfect for your vocal.

My wife sometimes asks me "What are you doing in there that keeps you so busy?" Well ...
