I need help with an inventory script for a large environment

So I've been tasked with building a PowerCLI script to dump an inventory of our VMWare virtual servers into a CSV document.  The inventory needs to include the servers Host Name, Domain, OS, UUID, IP assress VMWare Version, Power State, Used Space, Provisioned space, & Memory.  I have a script that I've been working on that provides some of the information, but stops providing the information after the IP address.  Also, it is PAINFULLY slow to complete.  Can someone assist me in fixing this script, or provide a working script that can give me the inventory I need?  Thanks!

$start = Get-Date

# Create table for output

# Name DC OS UUID IP Version PowerState CPU MemoryGB UsedSpaceGB ProvisionedSpaceGB

$table = New-Object system.Data.DataTable "Results"

$col1 = New-Object system.Data.DataColumn Name,([string])

$col2 = New-Object system.Data.DataColumn DC,([string])

$col4 = New-Object system.Data.DataColumn UUID,([string])

$col5 = New-Object system.Data.DataColumn IP,([string])

$col6 = New-Object system.Data.DataColumn Version,([string])

$col7 = New-Object system.Data.DataColumn PowerState,([string])

$col8 = New-Object system.Data.DataColumn CPU,([string])
