Does anyone have any thougths or boilerplate for sub-contractor contracts where one of the intents of the contract is to prevent a sub-contractor from directly 'propositioning' a client for a given period of time. I'm looking for a sample clause as well as objective 'good faith' criteria for specifying the length of such a period (3, 6, or 9 months, or 1 or 2 years).

I'm also interested in hearing your opinions on how strong these type of agreements are, in other words, are today's 'right-to-work' laws so strong that any agreements attempting to prevent commerce between two parties are thrown out by the courts?

My goal is to come up with a simple, plain English type of agreement designed to protect my clients from being exploited by any sub-contractors I may employ. I'm not looking for the 'perfect' contract - just some general advice.

Thanks!
Malcolm
