Get a copy of Brian Lockyears "Farm Strips Guide" to start with. And if that doesn't help go to some local fly-ins and ask around. But remember that many strips are operated on the 28 day rule (planning problems) so you won't always find they want any new aircraft. If you do find someone ask if you could operate from their strip when they are also using it and see if they (and the neighbours) are happy. You might find this helps to get a foot in the door so to speak! It worked for me....
