I think you might be better off finding a good stock selection at a nursery for Red Japanese maples. Few bonsai places seem to carry, them, plenty of tridents though........
You'd have to look for a good one and then do the cutting of the branches.
I saw one I sort of liked, but waited too long to buy, it was gone when I went back. 200$ tree I needed to cut, but it would have made a nice bonsai tree indeed after recovery and the wounds to close.
I know where there are perhaps 20-30 nice pines up in the sierras.
And a few along the coast of CA.
Just have not gone to get them.
