Get an electrician to do it

Copper, 3 2/0 and a #4. You can probably downsize neutral to 1/0.
Would need to calculate. 2" PVC.

This question is almost a year old, I would think the service has been installed by now.

Please check the date of the posts before answering.

Also, people do not come here to hear they need to hire, simply answer the question asked. Single family homeowners are allowed to do their own electrical work. This is something professional electricians need to deal with.
