Electrical Wiring in the Home/wire size and type for underground service


I am looking to run a cable underground from my meter for a distance of 500 feet to service a  single phase 200 amp panel in my shop. What would you recommend as far as size and type in aluminum or copper wire as the most cost efficient way to do this job?

I personally aways use copper conductors to eliminate the possibility of future corrosion, so this is for copper conductors:
2 - 4/0 for the hot legs
1 - 2/0 for the neutral
1 - #1 for the ground

Keep in mind for a panel or sub panel a ground rod must also be installed and connected to the ground bar in the panel and you will need a #4 bare copper conductor to attach the panel to the rod. Also depending on your location two ground rods may need to be installed. Check with the local inpsection department for this and how far apart they must be if two are required. Thanks J
