I agree with LBR, That is a time consuming project, what I do is watch Ebay sales and when I find a dozen or so that I think are good and cheap I bid.
I just got one dozen with practice tips beautifull fletching and colors for $20 plus $4 shipping , you can't beat that. I also got some unused vintage arrows with broadheads for $24 and they are Flawless.

I have wasted a lot of time building arrows, no more ebay is for me.
