These prices and pieces are all relative. I am most expensive hourly because I don't prefer to work on one hour projects. Pricing is better for larger projects to promote that work. Generally I can get about a panel/page of paper in a day if we are working with large black and grey. Geometry, detail and color add time. I always lean in to designing for impact and value to you, not unnecessary details and cost to you. The more control you allow, the better the price.
