Hello. My name is David Sharples, owner of an Australian-based graphic design firm, Blackball Design. I've read over your project and I'm interested in helping you with developing scientific illustrations for you from your figures and data. I've worked on similar projects like this before, once for a client developing science textbooks, and I'd be interested in chatting with you further about the kinds of images that you'd like developed and how you would like them to look. I'll be able to develop a range of concept designs of each image, cleaned, shaded and coloured to your desired specifications, and refine them as many times as needed from your feedback until you are satisfied with the end result.
I've worked for over seven years with the Adobe Creative Suite, working with Photoshop and Illustrator to create sophisticated graphics for a wide variety of clients, including the aforementioned textbook developer. For some examples of my graphic design skills, feel free to check out my portfolio here on Freelancer and my online blog portfolio ([login to view URL]). I'll also be happy to provide you with further examples if you are interested.
I've placed my bid for $300, $50 per illustration, covering concept development, refinement and finalization, within five days. Let me know if this works for you or if you have any deadlines you need these materials completed my. Let me know if you'd like to talk further and I'll be happy to chat.
