Judging from the video uploads for YouTube it looks like they focus on a geographical area based on analytics and interest from cold calling. they then get the film team contracted for a day and sweep through as many businesses as they can in a short period. so I think that is how production costs are cheaper as all clients are sharing the up front cost. for me the main issue is IMO no customer should count as a receipt until they accept the product and big should be funding all new filming now out of existing working capital
