Lifesize color illustration (152cm tall) of female comic character

I am looking for a skilled illustrator to create a lifesize color illustration of a female comic character of my own design. The style of illustration should be cartoon/comic. I have the idea for the character's appearance, but I am open to the illustrator's interpretation as well. The ideal candidate for this project should have experience in creating realistic and detailed cartoon/comic illustrations. The final illustration should be 152cm tall and reflect the preferred colors for the character. Character shall:
- Have skin tone as shown in the color poster
- Have hair color as shown in color poster, including the purple highlight
- Should resemble the black and white images of character (does not have to be exact but have close facial features [shape of face, eyebrows, glasses, etc])
- Have the green "T" pin on her left chest in (see sketch and pin for color)
- Have a white shirt and grey pants (with applicable shading, artistic freedom)
- Black shoes (not high heeled)
- Holding a generic laptop (see stock photo)
- Have her basic angle and pose like that in the stock photo (like the blond girl holding the laptop).

A basic approved sketch is required before work on final product.

Deliverable will be a JPG or PDF of image. It must NOT be pixelated when at that size as it will be printed out as lifesized.

Ownership of image will belong to me but artist is allowed to use image for their portfolio.
