John, Thanks so much for getting back to me so quickly. I really appreciate it.
I found some low-cost zip code polygons at GISDataShop that I'm going to try and build into my service areas. I tried using the Tiger shapefiles, but since I only have Google Earth and not the full version of Google Earth PRO, I figured purchasing a low-cost KML was probably my best option. I anticipate only having about 10 or so polygons needed, and worse case, I can separate these polygons into separate KML files if there are any issues with rendering (not the most elegant solution I know, but this is a pretty primitive mapplet as is). Thanks again for your help. Have a great weekend!
