I am an experienced illustrator, concept artist and high-end digital painter. I work in a broad range of styles and quality levels. I encourage you to take a look at my portfolio here (Illustration mostly), with my name at blogspot or CG society, although it's not complete there.
My pricing goes for the concept of a single interior OR exterior of a non extremely complex ship in a finished digital painting, plus orthographic views for modelling. If you give me a detailed description, I will give you a more accurate quote and an estimated delivery time.
I will be available for work next week, but contact me if you would like to discuss your project, see some samples, or have a pricing list.
Thanks for your attention.
