Hello, Chela. Hooray! That is wonderful that you are making such a great effort to maintain a green office.

Fantastic!
I also have a welcome packet. Although I too aim to be totally paperless, I have to admit that I also rely on printed material for certain things. And like you, I always opt for the recycled paper. Kudos to you and to everyone who goes this extra small mile.
In Word 2010 there is an option for saving your documents as a PDF, which makes printing and scanning totally unnecessary. I have created a single document entitled "Welcome to eXPERT Business Support Services," which consists of a short letter offering rewards for referrals, a copy of our agreement/contracts, my emergency plan, a contact page, a FAQ page, and depending on the client, I also include information about the specific service I'm going to be providing. I email it off, and even though I prefer not doing this, I offer to mail them the packet via US mail. In most cases, that is never necessary.
Congratulations on your business and I wish you all the best!
