I travel to Lancaster, Pennsylvania and purchase my gourds from Amish gourd farms.  Each one is uniquely hand-crafted. They are cleaned out and drilled with a Dremel.  I use leather dye, acrylic paint and polyurethane spray to coat the finished gourds.  Most are mounted on a base and include a single light cord that clips into the back of the gourd for illumination.  The gourds are adorned with various decorations.  I have a new set of ocean themed gourds that I am working on for the 2022 season!
