First, I don't think that you will find a dairy to sell you a young cow. You can ask but they are not going to part with their younger milkers but you might be able to get a calf if they have enough replacements. I would think that because you want it for 4H and to show that it would have to be registered and I think you'll have to pay at least $700 for a day old jersey heifer.
I found these on usjersey.com, use the directory. You might find others that you are willing to travel for. I only looked at the dairies that have over 50 head milking.
