You are correct that the low MC is critical to avoid moisture problems after manufacturing.
 
If you need only small quantities, it is indeed possible and easy to use a heated room to dry the wood from 15 MC down to 7 MC. Incidentally, for tax purposes it should be called a lumber dry kiln, not a heated room; a kiln is a piece of equipment. (Use the name “lumber dry kiln” so that it is not confused with a ceramic or pottery kiln that gets much hotter, and also looks different.)
 
Because of insects, you do need to go to 133F within the wood, even in the center. This will kill all insects and their eggs.
 
Once kiln dried to 7 MC, we do need to store the dried wood at the correct humidity (35 RH in this case) to avoid moisture changes. Our shop should be at the same RH level.
 
Finally, have you checked to see if there is a well-run custom kiln operation around you? This might be exactly what you need but you would not have a capital investment.
