Have you thought about looking at what the organization would like to obtain and overall what your organization's mission or objective is? This sounds like metrics to me, however Jack Fitz-enz has a Great book out that could possibly provide some insight into your question.

You can do a lot of your own legwork on contracting, yet an attorney's review is best.
There are several Consulting books with samples. Also www.nolo.com offers basic free information. Determine those aspects of your work/business that are most important for you and your clients to protect. Contracts set a tone for your working relationships. Some consultants work with an Agreement Letter.

Coastal Living; I understand wanting a contract to protect you, but I've noticed that a lot of fine consultants work with a letter of agreement or a very simple one page contract. So it isn't necessary to frighten the client with a lot of legalese. If you are clear on what you are planning to do in the engagement, and when, and what will be required from them and from you, you probably have most of what you need. A letter expressing that may suffice.

However, I do think there are some agreements in Elaine Biech's book of basics for consulting.

We at Consulting Today have never collected a set of documents for new practitioners - perhaps we should have. What should be in it if we did?
