Our scenario is we have a form that gets submitted for approval.  An email is sent to the manager to approve it.  Once the approval or denial is received, the form goes to the finance department to process.  Here's where it gets sticky and I can't figure out how to do it.

1) We want the form to go to the Finance department within 15 mins of it getting approved.

2) If the form is not approved within 24 hrs, we want a reminder email to the manager to approve the form.

3) We want this to continue for 10 days otherwise, we would deny the request.

If you have a suggestion, it would be helpful if you can put the actions in order that you think it would work, because I have tried using different combinations and I'm about to give up.

Thank you in advance.
