Hello,
I'm interested in this project because it looks to give some creative freedom while allowing a good amount of input from you.
Let me tell you a little about my process: First I start off with digital sketches of a different variety of numbers to get a feel of what you're looking for. After we decide on the look I finalize the sketches. Then after feedback, I begin the solid line work, and after that I move into color.
Since this seems to be more logo based work, I'll be using vector line work in Illustrator for the final phase, with some minor photoshop for touching up the look.
If you have any questions about my process, feel free to contract me.
