Call Transfer script to return unanswered blind transfer after 10 second timeout

Hi all, not sure if someone can help me with this or not, but of course happy to pay a fair rate for someone to help me with this, as the subject states, reception extension puts many calls through to other extensions but if unanswered by target extension then reception would like the call bounced back to them, let me know your quoted rate to deliver said script, I know very little in the way of scripts...otherwise I'd give it a go myself.
