Very difficult question. The price of home inspection depends on sq. ft. of the house, location, number of kitchens and bathrooms and so on. You can get a list of International Association of Certified Home Innspectors(the biggest inspector's association in the world)certified inspectors here: http://www.Nachi.org/ny
Be aware of the unbelivable sheap inspections you can find for example on creigslist. First, check the NYS license, second check the affiliation with inspector's asociation.
