He is the Director of Mass Wildlife. He will be able to inform you of everything you need to do to obtain the permit.
Which is 100.00 a year, and you are subject to random inspections if they so choose, as well.
Pretty much, its not hard if you can show a knowledgeable understanding on the care of the species, and provide for it, a suitable enclosure.
Demonstrate competence and you should have no problems obtaining the permit!
