Some DJ's certainly do depend on repeat business. 85-90% of my business is someone I have worked for before or has referred me or seen me at an event. I did an event about a month ago there were 5 couples there that I did their wedding in the last 7 or 8 years. There's almost always one couple that I have played their wedding at most events I do. I've done several 25th anniversaries that I did their wedding.
There is one young girl that I have done a Birthday party for since she was 8 years old. We did her Sweet 16 this year I've been doing one for her younger sister for 4 or 5 years now.
If it wasn't for repeat business I'd actually have to work hard at getting gigs lol
I can see how that works in your region.
About 15-20% of my gigs this year were by previous customer referral. Another 25% were booked by the talent agency, and those clients come to the agency via referral usually by the venue, or their wedding planner. Some come from Wedding Wire. The rest of my direct bookings were gig masters or google adwords. We were completely word of mouth, and referral up until the internet got popular. Then things changed.
As far as Chinese lighting. There will certainly be a difference between a Chinese wired up light for $50 or less, and a Eternal Lighting Battery operated Cube light that costs $349 each. I'm not saying they are the same. However, they do both provide up lighting. If battery powered is not essential, then the Chinese light for $50 will return a better ROI. Ever hear of "Buy low, Sell High"?
Sure we can say, but the Chinese lights will break, or malfunction...it's possible. But the malfunctions are low. Not as low as the higher priced fixtures with better quality control, but still low.
The Chinese up light can be paid for in 2 up lighting add ons, where as the $349 light will take many add ons to pay for the light. To someone that doesn't book Up Lighting on 15 or 20+ gigs a year, the Chinese light is a much easier purchase to make.
I can certainly say that I do not see any "lighting quality" difference between a no name brand 7x10 watt fixture, and say an American DJ Flat Mega Par. If I compare a 7x10 watt to the small Chauvet Slim Pars...well the 7x10 watt can get brighter. The Chauvet slim pars might last longer before they die out or break, but that is debatable too.
The industry use to use par cans with halogens and gels on top, and that was the standard. What really changed that all of a sudden requires dropping $250 to $400 on a LED up light fixture for weddings or parties?
