Sheesh -- $10/pound?? Maybe you can retire into beekeeping!
Since you want to get the most bang for your honey, your cappings are your best friend. Wash your cappings in a 5-gallon bucket, in about 3 gallons of water. Strain that cappings wash into a clean bucket through a regular kitchen strainer. The resulting must looks muddy, probably has a bit of wax floating around -- none of that will hurt the final mead. Test it with your hydrometer and you'll find that you are well on your way to a good SG for a primary ferment, without using a drop of your market honey.
You'll need to add more honey to the must, but that can come from your uncapping tank and not the "market" tank. Get the campdens in, then pitch your yeast as soon as you can. Otherwise it'll start fermenting on its own, and you'll have adventures in wild yeast ferments.
As far as the wife not liking a straight, commercial mead... it might be the mead. I find the commercial show meads to be FAR less interesting than a homebrew. Hopefully she'll give your experiments a second chance!
I've only had one person balk at $10 a pound. Everybody else has been thrilled to pay it. I think they were skeptical at first, but after discovering the difference between store bought and real local honey, come back and tell me how much they love it.
And that was for a light amber wildflower honey that I thought was just O.K. If I get another crop of this wonderful white/yellow honey that I've gotten before from the fall harvest, I'll cream it to prevent crystallization and likely get $15/lb for it.
I'm sure I could sell it all at a lower price, but I'd rather slowly expand the market of customers that would pay a high price and make mead with anything I can't sell, than cut the price and get rid of all the honey for the same amount of money. I'd rather sell 50#s at 10/# and have 50# left over to do what I want with, than sell it all at $5/#. In fact, I think the end profit would be better, because I'd only have to buy half as many containers.
I do plan on retiring into beekeeping at some point.
Thanks for the thoughts on the cappings, although I usually strain them into the same tank as the market honey, so there probably isn't much more than a 1/4 cup per super left trapped in the cappings. All the honey from the uncapping tank gets strained into the bottling tank and get's sold right along with everything else.
