Build and maintain client map

I am in need of building and maintaining a client/prospect map for my network marketing business. I have a mailing list that I need to merge with a report of the rolling 3-month sales volume. I then want to map that data out so that I know which areas to focus my energy when arranging trips to support my team across the US. Also, I would eventually like to add several categories to break my team into so that I can be more strategic with my growth planning. A common mapping tool (like Maptive or MapAnything) is preferred for long-term stability. My team is currently 350, but growing at 30-50 per month.
