Applescript Execute Shell with Input and Admin Privileges - bash

Question

I'm trying to write an automator service to fire up virtualhost.sh in a terminal.
Using the Services context menu the dialog opens to ask for the name of virtual host, then runs an applescript to launch terminal and pass in the input text.
What I want is to pass in my username and password to admin privileges so that I don't need to pass it in the terminal with sudo.
This can be done with do shell script but that executes a bin/sh and the virtualhost.sh is a bash script so I get the error bin/sh: virtualhost.sh command not found
Alternately I can use do script with command but this doesn't allow me to pass in the user name and password.
My code looks like so:
on run {input, parameters}
set vhost to "virtualhost.sh " & input
tell application "Terminal"
activate
do shell script vhost user name "user" password "pass" with
administrator privileges
end tell
end run
This produces the bin/sh error previously mentioned.
With do script with command
on run {input, parameters}
set vhost to "virtualhost.sh " & input
tell application "Terminal"
activate
do script with command vhost user name "user" password "pass" with
administrator privileges
end tell
end run
This produces an escaping error: Expected end of line, etc. but found property.
Is there a way to do this correctly?

Not specifically familiar with AppleScript Studio, but you can do it in plain old AppleScript (which appears to have the same issue) if you provide a full path to virtualhost.sh. (Also, Terminal is not required with "do shell script".) Example:
set vhost to "/usr/local/bin/virtualhost.sh " & input
do shell script vhost user name "user" password "pass" ¬
with administrator privileges
You can also extend $PATH (which is by default /usr/bin:/bin:/usr/sbin:/sbin with "do shell script") to include the path to virtualhost.sh, e.g.:
set vhost to "{ PATH=$PATH:/usr/local/bin; virtualhost.sh " & input & "; }"
do shell script vhost user name "user" password "pass" ¬
with administrator privileges
If you want a relative path, you can put virtualhost.sh inside the script application or bundle (e.g. in Contents/Resources), either in Terminal or by control-clicking and choosing "Show Package Contents". Then use "path to me":
set vhostPath to "'" & POSIX path of (path to me) & ¬
"/Contents/Resources/virtualhost.sh" & "'"
set vhost to vhostPath & space & input
do shell script vhost user name "user" password "pass" ¬
with administrator privileges

Per the comment on my other answer, I'm posting a secondary answer more in the spirit of that there's a will, there's a way, but it's a different, more dangerous approach. However, it's the only solution I can think of to this particular requirement (to get the interactivity of Terminal, but without having to prompt for an administrator password while running a script as administrator).
This solution runs Terminal as root, which is what do shell script "command" with administrator privileges does. This is dangerous because you have an open Terminal window with root access, so carefully weigh benefits against potential consequences of, say, opening a new Terminal window and being at the Bash prompt as root.
For this reason, the Terminal instance that is opened is killed upon completion of the script; if the "kill" command is removed, be aware you'll get multiple instances of Terminal, rather than multiple windows within the same instance.
No idea if this works in AppleScript Studio (it works in AppleScript Editor), but I can't think of any reason why it wouldn't.
set input to "some_input"
set vhost to "/usr/local/bin/virtualhost.sh " & input
set kill to ¬
"terminal_pid=$(</tmp/terminal_pid); rm /tmp/terminal_pid; kill $terminal_pid"
-- launch Terminal as root, and save its process ID in /tmp/terminal_pid
tell application "Finder" to set beforeProcesses to processes
do shell script ¬
"/Applications/Utilities/Terminal.app/Contents/MacOS/Terminal " & ¬
"&> /dev/null & echo $! > /tmp/terminal_pid" user name "user" password ¬
"pass" with administrator privileges
-- wait until the new Terminal is confirmed to be running
tell application "Finder"
repeat while (processes is equal to beforeProcesses)
do shell script "sleep 0.5"
end repeat
end tell
-- Perform script in root Terminal window that we just opened,
-- and kill Terminal when done to prevent open root prompt
-- and multiple processes.
tell application "Terminal"
activate
do script vhost & "; " & kill
end tell
-- optional: wait until Terminal is gone before continuing
do shell script "while [[ ( -f /tmp/terminal_pid ) " & ¬
"&& ( \"$(ps -p $(</tmp/terminal_pid) -o%cpu='')\" ) ]]; do sleep 0.5; done"
