Yes, I've done many events in what are lesser affluent markets than that of North Jersey. Some with avg household income levels not much higher than that of Oneanta, AL. However, I'm of the perspective that people who value something... anything... will try to find a way to make it happen. Some ultimately just won't be able to, some may make financially bad decisions to make it happen, some will sacrifice other things, and some have responsibly been saving to get the things they value.True. I look at you, and how you've crafted your brand and marketing and it inspires me. Breaking out of that "price leader" mentality is super difficult for a lot of us. I also theorize that in Mix's case, a lot of it is the culture and the clique he's around. If all you know are people with no money, then that's your market and will determine the price you can draw. In your case, my perception, you're in a premium market and with high-value people. It enables you the maximize your profit potential, although I realize you've succeeded in some lesser-affluent markets. In my own case, Alabama is one of the poorer states in the nation, not to mention that I'm 50 miles away from the nearest large city. It remains to be seen but I suspect that by the time I get a few more years under my belt and get a few more construction projects done (paved parking, concrete area out back complete with garden, etc) that that $7.5k will look more like $10k and my top end should be $12k-$15k. If I can keep my costs at $3k-$5k then I think I have potential to start putting up some real numbers. It's all just a process. You come up with a game plan, execute, adjust, execute, etc. etc.
To further put this in perspective... Rocky River OH, Richmond, VA, or Fayetteville, NC have household incomes 30-50% less than towns in North Jersey where I often work. Yet, in order for them to book me, they have to pay 2.5-3x MORE than NJ clients to book me due to travel costs and the inability to book other events.
You need to determine where your VALUE is, and then learn to properly portray and MARKET that value to the right set of eyes. I think it's why so many are telling you to stop trying to do everything, and focus on one thing and do it super well. Create a stunning venue, that is well ran, offers unique immersive experiences, and has an owner that is attentive, responsible, responsive, and dedicated, and you will have a winning formula. Do too much, certain categories will take a step back and a weak link starts to form.
