How can I obtain a N.J. Fireworks permit so i can legally have a display at my house?

i know if you get a permit you can legally have all fireworks and set them off w/out having to worry about state troopers confiscating my stuff. can some1 give me a link to a form i can fill out??
Update: i have 5 acres and a large portion is fenced in where i set everything off.
