Re: A good left-hand bolt action ??
+1 for the above. If you are comfortable looking at a gunshow, feel free to look at what is available (new or used) on that day. With 30-06 rifles you have the most common caliber made for hunting guns; left handed guns are less common but also will be slower to sell for the dealers who have them. Also consider .308 or maybe a Savage lever action in 308 or 300 savage if it feels shootable to you.
