It's never completely fair to use an actual price number in a poll like this. It would be much more accurate to talk about pricing relative to the local market.
It's also impossible to get a real number on what DJs locally cost. You can see what prices they advertise, but plenty of small business owners offer deals and reductions frequently. The advertised numbers are misleading.
So with highly imperfect data, we all try to price ourselves where we think we are in the market and relative to what we think we can get. And then this cycle goes round and round where you hear little pieces of data.
Some numbers are so obviously very low that it's easy to beat them up. So Mix gets beat up every time he actually tells us he works for < $300 to bring his big ass speakers out. Some numbers are obviously high, so when Taso gets $3,500+ for a gig everyone has a tinge of envy.
I would argue this always comes down to evaluating where you fall on the Product, Sales, Marketing Matrix (I'm making that term up).
If your product is not at or above average... you have to start there. It's not just gear, it's all of it. Does your set up look tidy and professional? Are you easy to work with for other vendors? Do you communicate well and quickly when needed during planning? Are you good at selecting the right energy tunes for the moment? Can you mix and blend when it's appropriate? If you offer lights are they 30 year old spin and pukes, or are they coordinating with the music properly? Do you have good instincts on what is important at any given time and yield the spotlight for the benefit of the overall client and guest experience? I could go on forever.
If/when your product is good, you've got to be able to communicate that and instill trust. This comes down to how you sell. Do you demonstrate command of your craft without sounding like a blowhard? Can you explain why you are different from any of your other GOOD competitors - not just the crappy ones? Is your pricing easy enough to understand? Can you accurately describe what clients should expect from working with you quickly? Do you make the prospect feel heard in the meantime?
Last but not least, it's where your leads come from - your marketing. If you're being referred, you're likely on a list of 1 - 5 providers, but perhaps most commonly 3. You are in a small competition and have good odds. If you're not being referred, you have to fish in broader pools. On WeddingWire/Knot/Google you might be 1 of 200. Granted, you can pay for top placement, but it's pricey. As a result your lead quality is going to be weaker and you'll just statistically have lower odds of closing. That's ok as long as you are calibrated. And more at-bats means you can improve on the sales skills with a higher number of reps. But the goal is relying less on the big pool sources and more on reputation and brand as you do this longer.
That's the whole thing, but small business owners seem to complicate it all the time. The price you can get will come down to how much demand you are generating, how good you are at communicating your value, and whether your product is actually good.
