There are major differences between the role of a manager and that of an agent. Agents are licensed by their state, have specific responsibilities, and their job is to find and negotiate work for their talent. Agents that represent actors need a SAG franchise license as well, while print agents do not. Managers are almost completely unregulated, but for example here in Calif, they do need a Talent Management license, but technically may not negotiate a contract on behalf of their client (the talent) unless they happen to also be attorney. Yes, that rule gets violated all the time, but that is the rule. I actually took a course a few years ago at UCLA on become a talent manager and decided against it for a variety of reasons. (For more on this, check out this
article I found with a simple Google search. While it comments mostly on the music business, the principles are still the same).
Models don't need managers ever (unless they get to the level of Cindy Crawford) because everything they do can be negotiated by their agents and a manager is just another percentage to give up. At some point they might need a business manager, or if they start to expand their career beyond modeling, a real talent manager, but certainly not at the beginning stages of a career. A model who wants to know how to get started, or what jobs she should or shouldn't take, can talk to other models and photographers without adding the baggage of a manager.
What most people are describing when they think of a model manager for an online model or local model, is really a "screener" and/or "reference checker". It is quite understandable that such models would seek assistance in detemining whether someone is legit, or more importantly, safe, but that is quite a different job description from "manager". Real managers are supposed to guide a career and help promote the talent, without targeting a specific job - its a very subjective job description and hard to measure performance. It been my experience that almost all of the "model managers" I've met, haven't got a clue about how the real industry works, and their expectations and demands usually result in the model getting less work, not more.
That is why you'll probably find it difficult to find sample "manager" contracts. If you were to see a true management contract for actors, it would be a couple pages long and not have much bearing on the modeling industry at all.
