I've been doing graphic design for over 2 years now, with plenty of happy customers and feel fairly confident I can do exactly what you're looking for. I don't exactly have an amazing portfolio, but if you award me the project, hopefully that will change! I'd love to be able to add in some nice website mock ups.
I'm very good at simplistic, sleek and easy on the eyes designs, which is exactly what any website needs. I'm also quite good at illustrations. Feel free to look through my profile and portfolio.
All my work is done in Adobe Illustrator, and infinitely scale-able, so no matter how big so small your needs are, they'll look perfect. I also use photoshop and am very proficient in it.
I'd definitely like to hear more about what you're looking for. I'm open practically all day everyday, and will be able to communicate and work with you. I'm very enthusiastic about design, so you'll definitely get the best out of me.
