You can commission me.
My rate is quite simple, my usual rate is 15.00/hour for non commercial work and 30.00/hour for commercial work so basically I will work with whatever time I'm paid for, my times per illustration vary depending on how much detail you want me to add but know that I will always deliver a high quality product, the only thing that will vary is the level of detail I put into the image.
Just so you will have an idea of the pricing my Marvel Heroines were produced on an average of 8 hours per character, do notice that the backgrounds are quite simple though. Something with a more detailed Background will obviously take me longer to make.
If you want to commission me you can send me a Note or write me an email to firstname.lastname@example.org
