Best thing out there. Don't send him somewhere, build the bond between you and him. No treats, show him you are alpha (without breaking his spirit... w/affection) and he will do anything.
I had never had obedient dogs growing up, and my wife (involved w/ golden retriever rescue) brought home a dog just like you describe...found someone local that taught the same concept and we went. Tremendous success...happy to talk more.
