macrodontia cervocornis Questions concerning the preservation of a Sabertooth longhorn beetle(Macrodontia cervicornis)

[Samuel]

Good day, I found a 15.24cm male Macrodontia cervicornis and am wanting to dehydrate it and pin it however, I am new to preserving insects and have a few questions.  The first one is what would be the best way to dehydrate it for transport. The other question is where would be the best place to sell this specimen.  I would really appreciate it if someone could answer these questions and maybe add step-by-step directions for dehydrating, transporting, rehydrating, and pinning(if pinning is the best option for this massive beetle).  Thank you very much.
