Adwords URL Checker Script Development

I need someone to modify an existing script to my specifications. An example of the script can be seen here [login to view URL] I'd like to modify this adwords script to meet my customers specifications. The script will need to be able to send out an email daily if any urls lead to 404 error pages or if the URL doesn't contain the "Mkwid" within it's string. The logic for this script is very simple, and most of the work has been done by adwords. You will simply be asked to modify it to meet our email sending specifications, and checking to make sure the url string is complete.
