Great minds think alike. I also thought of making a tincture and then boiling it down to a very high concentration. I don't think it should be too hard to get the tincture into capsules. There are some capsule filling devices that are very inexpensive (like $10-$13). Basically they serve as a rack to hold the capsule bottoms. To actually pick up the liquid and insert it into each cap I would suggest an adjustable pipettor (also spelled pipetter).

The pipettor is like a large pipette that uses inexpensive disposable plastic tips. You adjust the pipettor to pick up the same amount of liquid each time. I believe each 00 gel cap holds about .9 ml. You put the tip in the liquid and press the button on top of the pipettor and it will draw up the amount that you have set. This device will let you pick up just enough to fill each individual capsule. It's a pain to have to fill each capsule one-by-one, but at least a pipettor should make it easier.

Pipettors come in a wide price range... You might want to check out Ebay.
