Easy way to obtain valuable testimonials that work for you

If you would like to obtain client stories or testimonials, you can interview people with a set of questions and condense it into what you need, and then send it to them for their approval.  If you need something from them on letterhead so you have a record of their approval, you can send it to them, typed and on a plain piece of paper so all they have to do is photocopy onto their letterhead and mail it back to you in a self-addressed stamped envelope that you provided them.
