I prefer to get paid per job instead of hourly. I have done both, but I think hourly ends up being more work for both of us, so I shy away from it. But if it's absolutely necessary I can do that too.
I prefer to communicate often so that I am clear on what you need and you feel comfortable with my progress. This is the only way I know of ensuring that the final work is completed in a way that makes you as pleased as possible.
I am on the east coast of the USA (EST Time) and typically work early in the morning until mid afternoon. If a project requires it I can work part time over the weekend but typically try to avoid it.
