The Contract Reporter is FREE
The New York State Contract Reporter is "New York’s official publication state procurement opportunities from state agencies, public authorities and public benefit corporations. The NYSCR is now free of charge for general access." Also check out OGS' Procurement Law, Guidelines and Procedures and Seller Information & Bid Opportunities . Just as important, when you find a contract that may be expiring in the next several months, TALK to the purchasing officer associated with that contract. There is a window during which they can help a prospective business, but another during which they cannot.
