Sharepoint - Export all data to csv with powershell - powershell

Question

I am attempting to use a script provided by Thriggle See His Answer Here and am having some issues with it. It works almost flawlessly for what I am doing - EXCEPT - it doesn't export the Created By, Created Date, Modified By, and Modified Date.
Is there a way to add those fields into the script?
Here is his script:
$url = "$url"
$listName = "$list"
$path ="c:\ColumnsOfList.csv"
$web = Get-SPWeb $url
$list = $web.Lists.TryGetList($listName)
$fields = $list.ContentTypes | %{ $_.FieldLinks } | select Name, DisplayName
$items = #() #array to store objects representing list items
$list.items | %{
$item = $_;
$hash = #{}; #hash table to store field name-value pairs
$fields | %{ $hash[$_.DisplayName] = $item[$_.Name] };
$items += new-object psobject -Property $hash }
$items | Export-Csv -Path $path

You could try this one.
Here is my test code.
Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue
#Get the Web
$web = Get-SPWeb -identity "http://sp:12001"
#Get the Target List
$list = $web.Lists["OrderDetails"]
#Array to Hold Result - PSObjects
$ListItemCollection = #()
#Get All List items where Status is "In Progress"
$list.Items | foreach {
$ExportItem = New-Object PSObject
$ExportItem | Add-Member -MemberType NoteProperty -name "Title" -value $_["Title"]
$ExportItem | Add-Member -MemberType NoteProperty -Name "OrderDate" -value $_["OrderDate"]
$ExportItem | Add-Member -MemberType NoteProperty -name "CreatedBy" -value $_["Author"]
$ExportItem | Add-Member -MemberType NoteProperty -name "Created" -value $_["Created"]
#Add the object with property to an Array
$ListItemCollection += $ExportItem
}
#Export the result Array to CSV file
$ListItemCollection | Export-CSV "C:\Lee\ListData.csv" -NoTypeInformation
#Dispose the web Object
$web.Dispose()
