Writing an offer and software available

I am new to the profession and was wondering if their is an inexpensive source to find legally binding “Offer to Purchase Real Estate” software and other related forms for Maryland?

Ideally I would want something that I can download and use in MS WORD so it is easy to edit and update. I have the basic forms however who wants to re-type 10 zillion words.

Can you help me?

Thanks, Grant
