I teach from 8 AM to 1 PM PST Monday through Friday. I'm available for calls, or in person meetings between 1 PM and 6 PM PST. Most of my project working hours occur at night so that I can work without distraction.
I do expect a deposit before I begin and then the rest when the project is live to the public unless the project is expected to go for an extended period of time, then we must negotiate terms specific to the project. I am always happy to continue edits and additions once the project is live, but at my hourly work if it is outside the original scope of the project.
