Price and Availability of white cedar logs for Shingles

[kgb12158]

I have a LT40 HG Woodmizer mill with a belt type shingle mill option.  I would like to make my own white ceder shingles.  
I'm in need of logs so 1 question is who has them and what will they cost per BF.  OK that's 2 questions.
I'm located on Rt20 west of Schenectady NY in Duansburgh.  I could pick up ~1500BF with my trailer.  
Does anyone have experience in cutting shingles this way?  Any idea about yield?
How long a shingle is practical with the resaw belt?
Too many question so little time.  
Thanks for any help you could offer.
I should say this is update NY

Hey man, you're not far out from me, I'm near Greenville/westerlo area. I would try cooksburg lumber in Preston hollow, they run a pretty good sawmill there, not sure what current prices are but I believe you can buy log lengths from them, if not I know a tree service company or two in the area with decent stockpiles.

Any contact info?  I did find a few cedar logs out Madison NY area which I will pick up next week.  I know Cooksburg.  I bought some Hemlock a couple of months ago.  They were a little pricey but when you need the timber you need timbers.  I plan on trying some pine at first to see how the resaw works.  I will update the string as I go.

Thanks
