Herd of Huacaya Alpaca

I'm selling my herd of 4 registered Huacaya Alpacas, they have incredible bloodlines, there are 2 herd sires and 2 pregnant females. I bought the one female for $8000 and the other female for $6500, the one male was $4000 and the other was $3000. That's $21,500 for all 4 before the females were pregnant.
I'm asking $20,000 for all 4 alpacas or open to trades for property or other animals. I'm willing to take payments or sell them separately, now is the time to buy them so you can use them as a tax deduction (one of the only animals that are tax deductible).
I'm easy going, let me know what you have to offer
