1.Make sure they are Contracted (and look up the IRS's definition of a Contractor).
2. Get the PSD, CSS, images, and javascript if applicable. Also, get at least a couple HTML's all styled up so you can put it into your dynamic template more easily.
3. They'll need a lot of access to the app to figure out how it's assembled and constructed and they'll need to study every element that's present in the whole app so they know how to style it. I'm a designer/developer, so I'm not extremely familiar with the whole process of getting someone who is ONLY a designer. Also, the estimate is just that, an estimate. Don't trust anyone who says otherwise.
