Everything costs money.
The facade that matters is the one your client wears when they walk in the door.
If I spent Thousands of $$'s to have the room completely done with white drape - then I'm not gonna want to have a DJ with black road cases setup in front of that. I'm either gonna pay my decorator to include some kind of "booth" to hide the DJ gear, or find a DJ with a matching white setup. The "white" look is probably on it's last few years of use, and will completely disappear when the LED up lighting it serves runs it's course as well. Someday this too - will all be "vintage."
The point remains however, that no matter what the event theme, color scheme, or venue architecture.
It's an issue whenever and wherever DECOR is a priority. Fact is, decor is
not a priority expenditure for the largest segment of the mobile DJ biz. People planning the typical wedding go out of their way to locate venues with pleasing architecture and interior design specifically so they can avoid paying the extra cost of expensive decorators.
People with money to burn or guests to impress don't care about cost. They will book a log cabin and pay to have it decorated like the Ritz Carlton. Then they will book the Ritz Carlton and ask you to decorate it like a log cabin. There's a segment of this industry's clients that operate very much like Hollywood.
Don't buy a facade on the notion that it will somehow elevate your market position or attract a new clientele. It won't. Use whatever sensible means there are to make your setup conform to the spaces you work in, and expectations of the clients you already have.. In other words - look the part for whatever part you are playing and avoid upstaging yourself with setup elements that contradict each other.
At some events I do, a table and even black road cases are perfect, and at others there is weeks of planning to get a decor solution that is perfectly right. Other DJs who serve repetitive markets will offer up some predefined set options for clients to choose. These include common popular decor styles in White, black, gold, translucent, or illuminated glow themes. They also have to change these every other year to stay relevant in their market. These client's don't do decor repeats and they all run in the same social circles so, it's not as simple as buying a product and sticking it in front of you gig after gig.
