People can buy candles anywhere, you have to make your candles special and stand out from the crowd. I recommend better descriptions and photography. Also, you should pre-make some candles with a variety of scents and a variety of glasses so the customer can get more of an idea of how to customize if they so wish. And someone might like the sound of one of the pre-made ones and buy it. Have several listings with your pre-made candles. Just a couple listings that says "I will make a customized candle for you" isn't enough. Consider giving your scents names that stand out from the rest, and evoke a mood. For example "Key Lime Pie" sounds better than just a "Lime" scented candle.
