Holiday lighting in SoCal

Does anyone know a good whole seller for holiday lights in/near Southern California? A few guys on my window cleaning crew are preparing to do xmas lights for the first time this year, and I’m in the initial stages of planning. I’ve reached out to a few people on facebook, but couldn’t find anyone in my area to help with a whole seller. any info/advice is appreciated!

Does it have to be in Southern Ca? If so why?

American Lighting is out of Denver. Very happy with their customer service
