Hello Madhav, You can purchase an electroless nickel plating kit, a company called Transene used to sell this but, I am not sure if they still do. The kits are relatively inexpensive. The adhesion to PMMA may present an issue however I am not sure of this. If you would like to contact me directly please feel free to do so.
