Presuming this isn't going to be used for anything five figures and up, then I'd say the more important document for a freelance gig is the Scope of Work. The crux of the SOW is expectations. The contract - for (smaller) freelance work - imho doesn't come into play unless the expectation set (or not) by the SOW goes sideways.

While the contract defines the legal CYAs, etc, the SOW help define the relationship without all the heavy-handed language gymnastics.
