Ubuntu – Good pratice to create script to start/stop/restart service

I was wondering what is a good pratice to create a good script to start/stop/restart some service. I will try to make myself more clear, ok ?
Nowadays, I do something like this: let's say I would like to create a script to start/stop/restart a service, so I create a folder /company/service name/ and there put the start.sh and the stop.sh, which are something like this:

start.sh

#!/bin/bash
#VARIABLES
SERVICE_NAME="<service name>"
USERDEPLOYER="<service name>_deployer"
FOLDER=/company/<service name>/
KEYWORD="<keyword>"

#
#CHECKING SYSTEM STATUS
PROC=`ps -ef | grep $SERVICE_NAME | grep $KEYWORD | grep -v grep | awk -F" " '{ print $2 }'`;

if [ $PROC ]; then
  echo "$SERVICE_NAME is running!"
  echo "Stop then first!"
  exit
fi
###
#
#STARTING
if [[ `/usr/bin/whoami` == $USERDEPLOYER ]]
  then

    pushd .
    echo " "
    echo "Starting $SERVICE_NAME..."
    echo "cd $FOLDER"
    cd $FOLDER
    #COMMAND    
    <command to start the service> &

    sleep 20
    PROC=`ps -ef | grep $SERVICE_NAME | grep $KEYWORD | grep -v grep | awk -F" " '{ print $2 }'`;

    if [ -n "$PROC" ] && [ "$PROC" != "" ]
    then
      echo "OK: system started."
    else
      echo "ERROR: system process not found!"
    fi

    echo "script execution finished!"
    popd

else
  echo "User must be $USERDEPLOYER !"
fi

stop.sh

#!/bin/bash
#VARIABLES
SERVICE_NAME="<service name>"
USERDEPLOYER="<service name>_deployer"
KEYWORD="python"

if [[ `/usr/bin/whoami` == $USERDEPLOYER ]]
  then

    pushd .
    echo "Stopping $SERVICE_NAME......"

    #KILLING PROCESS
    processPID=`ps -ef | grep $SERVICE_NAME | grep $KEYWORD | grep -v grep | awk -F" " '{ print $2 }'`
    echo "Trying to kill process with key $SERVICE_NAME - ignore error messages below."
    kill $processPID
    sleep 10

    while [ -n "$processPID" ]
      do
    echo "Waiting process ($processPID) to shutdown...20s"
    sleep 20
        processPID=`ps -ef | grep $SERVICE_NAME | grep $KEYWORD | grep -v grep | awk -F" " '{ print $2 }'`
      done

    echo "Ensured process with key $SERVICE_NAME is no longer running."
    popd

else
  echo "User must be $USERDEPLOYER !"
fi

After that I create an user service name_deployer, than give the ownership to this folder and these scrits, start.sh and stop.sh, giving the permission to read, write and execute as well.

Then create the follow script in /etc/init.d/ as service name-service :

#!/bin/bash
#
#   Linux chkconfig stuff:
#
#   chkconfig: 2345 56 10
#   2345 56  
#   2345 10  
#   description: <description>
# Source function library.
SERVICE_NAME="<service name>-service"
SERVICE_USER="<service name>_deployer"
FOLDER="/company/<service name>/"

start() {

if [[ `/usr/bin/whoami` == $SERVICE_USER ]]
then
  cd $FOLDER
  ./start.sh

#NOT USER _root
else 
  cd $FOLDER
  su $SERVICE_USER ./start.sh
fi
}

stop() {
  cd $FOLDER
  su $SERVICE_USER ./stop.sh
}

#Body main
case "$1" in
  start)
    start
    ;;
  stop)
    stop
    ;;
  restart)
    echo "Restarting $SERVICE_NAME..."
    echo " "
    stop
    sleep 10
    start
    ;;
  *)
    echo $"Usage: $0 {start|stop|restart}"
    exit 1
esac
exit 0

Given the ownership to service name_deployer and the permission to read, write and execute.

Then add the service to the list of services like this:
/sbin/chkconfig –add service name-service (suse and others)
or
update-rc.d service name-service defaults (ubuntu)

And that's all!
Did you guys think this is a good approach ? I'm just asking 'cause I would like to create a good standard to this kind of scripts and procedures.
Sorry if you guys think this is a lame question but for me is very important this kind of procedure.

Thank you guys!
