Need script to run for each site then create site report then email to site specific personnel.

All I'm currently having issues with combining multiple scripts into one. What I need is to run my script against each site ou then create the site specific csv file by site name then email it to the site specific users. I have been told I need to use parameters and more functions the only problem is I don't know PS very much at all. The script I have is from cutting and pasting from different examples on the internet and trying this and that. Not sure if there is a better way to post the script if there is please let me know. Thanks.

$sites = "BG", "NG", "FT"

$ouList = "class"

$lastlogondate=[datetime]::Today.AddDays(-30)

$datecreated=[datetime]::Today.AddDays(-30)

$currentdate = Get-Date

$recipients = "First.Last-BG@**.**.***", "First.Last-NG@**.**.***", "First.Last-FT@**.**.***"
