Normally a stump grinder is called in, but just how tall are the stumps ? Is there a wood turner - etc - willing to help extract them ? The center of the stump isn't the place - you want to kill the tree or dissolve the wood ? The softer outer edge is the place to kill it.
But a wood person might dig and extract the trunk and roots - for the grain.
