If you want to find it today, you'll need to find a yard that sells to bulkheaders and other companies that need piling for piers and dimensional lumber for marine use.

I tried to get some shipped to WV last summer but the local lumber company's rep at the treatment company got more than a little snotty. Come summer, I'll order the stuff from a yard in NJ and go pick it up.

My experience is with mostly with utility poles. I tried to get some addtional information on the 2.4# CCA stuff, but it is apparently so specialized that a source is hard to find. It may be that it requires a special license to purchase.. There is still a bit of creosote stuff out there, but as far as I can tell it is not available to the general public. The OP might be around a Redcedar source... that might be his best bet all around.

Concrete pier would be the best way to go if you are worried about rot.
I built a shed using the laminated 2x in the ground and conventional lumber 2' up from there. Just screw or bolt 3-2x6 or 2x8 together about 6' long and leave the center section 18" shorter. Do your coventional lumber the same only opposite and slide it into the one that's in the ground. Lap joint so to speak.
Works sweet when setting trusses, do the same thing at the top with the center board shorter. The truss slides right in and stays there.
I got the idea from a Morton building.
I don't know if they still do it the same way, but I would do it again.
More work, but it works out well and has been there 20 years with no problems.

They do as of last November anyhow.

Did all that so fast, I really didn't get to see it happen.... But then, when you are a month behind on harvest and still doing beans & corn up here in snow-land, you don't have much time to watch. Any other year, and I coulda enjoyed watching the build from a lawn chair....

For the 3 sticks in the column, you don't want any 2 joints across from each other. Stager them anyhow a foot from any other. Some adhesive as well as nails probably is a good deal too.
