I have been telecommuting for many years now - its a great way to work and live the homestead lifestyle. So I put together this eBook a year ago...but just added it to my website.

It has a bonus section on how to get you HR folks onboard (including a draft Telecommute policy they can use to get you set up).
I hope you find this (and my other guides) useful.
