Oh Lorin (and Laura, too), I am sorry to hear this.
Here's what I want to tell you. You've just written out what an unsuccessful strategy is for you. You've just proven to yourself that this strategy is not working and you are working harder. That means you need to change it up. I say this because that has happened to me, too, and when I changed my strategy, I did better. Don't wait so long to figure out if your strategy is working. Change it completely and go at it. It takes about a month or a month and half (because of how LONG it takes for contests to end), to know if you did the right thing to EARN MONEY. Your loves and likes will also tell you that along the way, but the real proof is in MONEY!
"Quality" is a relative term. What you are looking to find is the "sweetspot" ... the place where CHs live, not where you want them to live. That means for each one you've got to learn what they like. Do they want something like: Thisincrediblylongdomainthatnobodywilleverrememberinamillionyears.com or must they have Word.com? It means you have to take risks.
One time, long ago, I posted in the forum that sometimes I submit names that I'm not all that crazy about. You'd be surprised how many times I've gotten loves and likes over those names that I didn't really love myself but I felt like that was the CHs sweetspot.
Change your strategy drastically! You can do this!
