deploying tricky exe's

So I have got abit further I can make the shortcut with a separate script:
param (
[system.string]$ShortcutName = "GaomonTablet",
[system.string]$ShortcutUrl = "C:\GaomonTablet\GaomonTablet.exe",
[system.string]$IconURL = ".\GaomonTablet\GaomonTablet.ico",
[system.string]$Desktop = [Environment]::GetFolderPath("Desktop"),
[system.string]$IntuneProgramDir = "$env:APPDATA\Intune",
[System.String]$TempIcon = "$IntuneProgramDir\GaomonTablet.url",
[bool]$ShortcutOnDesktop = $True,
[bool]$ShortcutInStartMenu = $True
)

#Test if icon is currently present, if so delete it so we can update it
$IconPresent = Get-ChildItem -Path $Desktop | Where-Object {$_.Name -eq "$ShortcutName.lnk"}
If ($null -ne $IconPresent)
{
Remove-Item $IconPresent.VersionInfo.FileName -Force -Confirm:$False
}

$WScriptShell = New-Object -ComObject WScript.Shell

If ((Test-Path -Path $IntuneProgramDir) -eq $False)
{
New-Item -ItemType Directory $IntuneProgramDir -Force -Confirm:$False
}

#Start download of the icon in blob storage
Start-BitsTransfer -Source $IconURL -Destination $TempIcon


if ($ShortcutOnDesktop)
{
$Shortcut = $WScriptShell.CreateShortcut("$Desktop\$ShortcutName.lnk")
$Shortcut.TargetPath = $ShortcutUrl
$Shortcut.IconLocation = $TempIcon
$Shortcut.Save()
}

if ($ShortCutInStartMenu)
{
$Shortcut = $WScriptShell.CreateShortcut("$env:APPDATA\Microsoft\Windows\Start Menu\Programs\$ShortcutName.lnk")
$Shortcut.TargetPath = $ShortcutUrl
$Shortcut.IconLocation = $TempIcon
$Shortcut.Save()
}

But ideally id like this with

New-Item -Path "c:\" -Name "Gaomon" -ItemType "directory" -force
Copy-Item -Path "Gaomon\*" -Destination "C:\Gaomon" -Recurse -force
New-Item -Path "c:\" -Name "GaomonTablet" -ItemType "directory" -force
Copy-Item -Path "GaomonTablet\*" -Destination "C:\GaomonTablet" -Recurse -force

It errors out when I have them together. Any ideas on how I can combined these to scripts so it does everything together firstly create the folders then the shortcut
