In Michael Boylan's great book, The Power To Get In, he tells about the Circle of Leverage letter.

What I'm looking for is someone who can create software to make the creation of these letters easier.

It would be a very specialized form of mail merge, basically.

Each letter must contain two lists, but each letter's list must have all the items, except the item that pertain to THAT particular letter. That is, letter #2 must contain items 1 and 3-10 from both lists -- letter #3 must contain items 1-2 and 4-10 from both lists, etc. (as well as the standard mail merge items (contact info, etc.).

Any recommendations on good quality (but inexpensive) work like that. (yes, I already know about elance + rentacoder, etc.)

Thanks!
