Hi there. Your project looks very interesting and I am very interested in it. I am an illustrator and comic artist with more than ten years of experience, so I believe I can do great job for you. Please, check my complete profile and portfolio, so you can get a better idea about my work. I can draw in various styles, so I am sure that I can match the style you need for your advertisement design. I also believe that communication is the key to any successful project, so if you want someone who is willing to work from sketch, under your precise directions - feel free to contact me. Best regards!
p.s: My price is maybe higher then prices of other members of freelancer community, but I think that my portfolio and reviews can say a lot about quality of my work. I draw with passion and I produce high quality work which is original and unique. Cheers!
