Undercoating in the Long Island area!

I'm not sure if this is the right section. But keeping the undercarriage of my Tacoma was a first priority for me! I'll call it detailing the "unseen", well form the top at lease. I was posting to say, I have a place on the Island (Suffolk County) that I work at and I am interested in doing this professionally at my shop. I was thinking of charging around $800 for the service and materials, with a warranty.

Wondering what other people payed to have this done anywhere else, and how much they may have paid, or if not what would be willing to pay.

Any input or interest is appreciated
