There is nothing illegal in possessing potassium permanganate. You local family pharmacy should be able to supply you with prepacked small quantities. In earlier times it was a common household antiseptic, and it should be available for this. Your pharmacy might sell this under the name Condi's Crystals - exactly the same thing.
For larger quantities, consult your telephone book for the closest chemicals wholesaler in the nearest large city to you.
