This forum is designed to help people repair their own electronics. There is a great teardown available here. There are also numerous companies and individuals online and all over the world that would be willing to do/show you how to do this task.

From now on your mac should boot from the new drive and use that as the primary disk while the old one acts as a secondary drive available for...
