Hi, I am Joel:)
I read your project description and saw the files. I am an illustrator with having a lot of experience in drawing sketches, technical and pen/ink drawing.
This is indeed an easy project.
Here you can see my past drawing project:

Your correction/suggestion may change our target turnaround time.
I am using Artrage, Adobe Photoshop, Adobe Illustrator CC for projects like this--deliverable files will be AI, PSD, EPS, PNG or JPEG.
Remember that revisions are 100% free until you are satisfied.
I can start this project as soon as I won the BID.
If you have any questions let me know - especially on project pricing.
Looking forward,
JOEL
