Contact your local agricultural station or conservation officer. They should provide you with free inforegarding best plants at lowest cost and even give you the nursery where the state gets such plants at discount. Here in NY they offer a free assessment by a forester/ conservation guy on how to manage your property and the get most value benefit to wildlife out of it etc depending on your goals. they also publish books etc on the subject for free and list recomended plants that grow well inthe area. and what wildlife benfits from each type. They even teach you how to make brushpiles and densto encourage rabbits etc.Checkout your own state/ county etc . Hope it helps.
