Using list items to create sites programatically

I am looking to programatically create sites based on items in a SharePoint list. The list has 4 columns, Name, Email, ManagerName, ManagerEmail.

The aim is to use PowerShell to create a foreach loop, that creates a site (using the "Name" column as the site title/URL) based on the #STS01 teamsite template, breaks permission inheritance, and then gives the Manager ("ManagerName") contribute access to the site.

Not sure where to start with this, any advice would be appreciated!

Cheers!
