Powershell script to stop service, wait until it's stopped, start the service, wait until it's running then continue

I'm new to Powershell scripting and am trying to write a script that perform the following steps:

1. Stop the service on a remote computer (Service is VWServicePE, Computer is Computer1 in this example)
2. Wait for the service to stop before continuing
3. Continue once it's confirmed to be stopped
4. Start the service on the remote computer
5. Wait for the service to start before continuing
6. Continue once it's confirmed to be running

What I have below works to stop and start the service but the looping is not right as far as it waiting for the service to stop/start before proceeding.  Can anyone offer recommendations?

$state0 = "Stopped"
$state1 = "Running"
$svc1 = Get-Service -Name VWServicesPE -ComputerName Computer1

$svc1 | Set-Service -Status $state0
do {$svc1.Status}
Until ($svc1.Status -eq $state0)

$svc1 | Set-Service -Status $state1
do {$svc1.Status}
Until ($svc1.Status -eq $state1)

This might work, I think you could go about this better though.

$state0 = "Stopped"
$state1 = "Running"
$svc1 = Get-Service -Name WSService -ComputerName Computer1
$svc1 | Set-Service -Status $state0
while($svc1.Status -ne  $state0) { $svc1.Status }

try this one man:

$path = "C:\tmp\"
$serverlist = get-content "$path\ServerList.txt"
$servicename = "<Display name of service>"

foreach ($server in $serverlist){
	$result = Test-Connection $server -Count 1 -Quiet
	if ($result -eq "True") {
		$servicetorestart = Get-Service -name $servicename -ComputerName $server -ErrorAction SilentlyContinue
		if ($servicetorestart.Name -ne $servicename) {
			Add-Content "$path\noservice.txt" -Value ("$server" + " " + "Service $servicename is not present")
		}
		else {
			#sc.exe \\$server stop "$servicename"
			#Start-Sleep -Seconds 5
			#sc.exe \\$server start "$servicename"
			Add-Content "$path\ServiceRestarted.txt" -Value $server
		}
	}
	else {
		Add-Content "$path\noping.txt" -Value $server
	}
}

you can also change the input type from the above default list of server into some members of certain OU with the following changes:

replace the following line
$serverlist = get-content "$path\ServerList.txt"

with
$serverlist = Get-QADComputer -SearchRoot 'domain.com/Custom Servers OU' -OSName "Windows*Server*" -ShowProgress -Activity

I just realized I pasted in the wrong thing but it looks like ITStystemEngineer's should work just as well.

Here would be my suggestion:

$service = "Service" 
$svc1 = Get-Service $service -computername computer
Stop-Service $service
do { $svcstate = get-service $service | select -expa status; $svcstate } Until ($svcstate -ne "Running")

@dmbishop - Just by way of explanation, the reason yours didn't work was because you set with
$svc1 = Get-Service -Name VWServicesPE -ComputerName Computer1
$svc is a snapshot of what was returned by that command.  The contents of that variable don't change along with the state of the service.  So, you have to query the status of the service each time through the loop.  I would also add a Start-Sleep command so you're not trying to check it many times per second.
