When it comes to contracts, there is no one size fits all. Companies or businesses will often have a standard contract that they will want you to sign while others expect you to come up with one that spells everything out from your end. Most of the time there are a variety of things contained in the contract that are negotionable, but as a contractor the biggest one to concern yourself with is your fee. There may be limitations on hours, which should also be negotiable. One thing of particular note for different situations would be Scope of Work – what they are expecting you to do for them.
