Funnel or Pipeline from lead to sale

Funnel or Pipeline from lead to sale

I want to be able to track my pipeline or funnel with a conversion rate from Lead to a closed sale (including the different stages of the contact or potential).

I can't find a way to group leads and contacts (or potentials) so that I can visualize a report with this pipeline.  It seems I have to have a report for leads and a separate one for contacts.  Is there anyway to consolidate a funnel or report throughout the whole sales cycle?

Basically I would like to see:

Leads    Potential Stage 1     Potential Stage 2      Potential Sale
#                #                               #                             #
%leads       %leads                      %leads                   %leads

Thanks...
