I am planning to be in Florham Park, NJ mid March for a business trip.  I am not very familiar with New Jersey.  I would greatly appreciate recommendations on providers or recommendations on nearby towns to search.  Thank you in advance.

Secaucus (Meadowlands) is, by far, the area that is most used by providers in the Florham Park neighborhood. Approximately 30-35 minute drive. If you are a member of Date Check you should scan that for ladies that will be around when you are. Less desirable towns are Parsippany, Whippany, East Hanover but all are closer. Happy hunting!
