Are there services where parties help you capture the proposal on video? Im located in orange county and wanted to see if there might be a service here that provides video. I think I sort of have an idea.
Look up videographers in your area. There are specific surprise engagement proposal photographers, but I don't remember the name of the specific website I saw since it wasn't for my area. I'm also in So Cal.
Can you Yelp up a few videographers? And call them? Or even a photographer.
I haven't worked with this vendor, but my SO's friend is a photographer out here and he recommends this guy as a videographer. http://chrisacefilms.com/
