I self-paid for a handful of labs a few months ago, including Vit D (and thyroid, and blood related stuff, and cholesterol, and a few other related things). I went in, the nurse drew some blood and charged me $150. A week later, they mailed me the results. None of this was done online, and insurance never was involved. I found a lab in town, asked their cash price, and they told me, and it was fine. Specifically the lab was associated with a larger medical facility, so call around to any local hospitals to see what they quote you.
