My Launch Daemon doesn’t work despite returning a 0 status

For some reason, the launch daemon I created will not run successfully at system boot. I have tried it as a launch agent but that also doesn't work.

This is my plist located in /Library/LaunchDaemons:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.inetmac4.status</string>
    <key>ProgramArguments</key>
    <array>
        <string>/bin/sh</string>
        <string>/Users/inetmac4/script/VMSTATUS/vmstatus_startup</string>
    </array>
    <key>KeepAlive</key>
    <false/>
</dict>
</plist>

Interestingly, the script does run correctly if executed manually, just not through the daemon. And when running launchctl list after boot, the status for com.inetmac4.status is 0, but the script didn't appear to ever run.

Any help would be greatly appreciated! I've Googled but none of the solutions out there that I've found will work for me.

EDIT: It should be noted that I'm trying to run it on a Mac Pro on 10.8.5

EDIT2: And the script:

`#!/bin/bash
#cd /Users/inetmac4/
#python -m SimpleHTTPServer > ~/outfile 2> ~/errfile < /dev/null & disown
cd /Users/inetmac4/Script/VMSTATUS/
./VM.sh  > ~/outfile 2> ~/errfile < /dev/null & disown`

VM.sh:

#!/bin/sh

#  VM.sh
#  
#
#  Created by INETMac4 on 9/12/13.
#
COUNTER=0

while [  1 ]; do

    perl VM_STATUS.pl
    let COUNTER=COUNTER+1
    sleep 5
done

and VM_STATUS.pl:

#!/usr/bin/perl
use Data::Dumper;

#-- the same command in list context



    my @result = `prlctl list --all`;

    shift @result;
    open (VMSTATUS, '>/Users/inetmac4/Sites/index.html');

    my @user_log = <USERLOG>;

        my $computer_name = $values[1];

        if (exists($hash{ $computer_name }) == 0){
            $hash{ $computer_name } = 'true';
            push(@user_status, $_);
        }

    }

        print VMSTATUS "<b>STATUS:</b> ". $columns[1]."</br>\n";
        if ($name =~ 'Windows 8.1'){

        }
        foreach (@user_status_formatted){
            my @values = split(/\\/), $_;

            if ($values[0] =~ 'LOGGEDOUT' && $values[1] =~ $name){

                last;
            }
            if ($values[1] =~ $name){
                print VMSTATUS "<b>User: </b>  " . $values[2] . "\\" . $values[3]."\n</br></br>";
            }

        }
        print VMSTATUS "<hr>";
    }

    close (VMSTATUS);
