Hello, I would be interested in completing your project for you!
I have plenty of illustrative examples in my portfolio, and I specialize in the artwork of human figures.
For a definite price, I would have to ask your definition of what a sketch is: do you envision it with color, just black and white(or colored) lines, monochrome?
Is it for private use or is this something that you plan to reproduce?
I could deliver the artwork within a day. I would be open to sharing some progress shots along the way as well. Say, a few thumbnail sketches of poses for the two figures, from which you could pick which one you like best+ add some feedback and then I would go to work to really draw it out.
All depends on how specific the artwork must be.
Alright, thanks for considering me and have a great day!
