Conditional Auto-reply email program (PC)

I am looking for someone to build a Windows program that will retrieve emails from multiple gmail accounts and send an auto-reply based on keywords in email subject line. Extra functionality would include support for multiple (15+) auto-reply message templates, delayed auto-reply timer (ex. send email 5 minutes after message is received), pop3 and smtp support (SSL connections). Example functionality would be "If I received an email with "warehouse jobs" in the subject then auto-reply template message "Warehouse" would reply to the email with a delay using the Warehouse message template. Future features may be added
