Character Illustrations to describe software service

Hi everyone, I am looking for a graphic designer or artist who can offer: Character Design, Concepts and Character Illustrations. We are a start-up company offering software as a service. We need to simplify our message and get across very clearly what our software does, how it benefits users etc. We want to use character illustrations to do this. Our system helps organisations develop and test complex decisions – it can be thought of as a brain. We want a consistent character theme to use throughout the marketing process, but each character illustration needs to show a different concept. Each of the illustrations will be roughly the same size (approx 3 inch by 2inch), BUT we should be able to use the character on its own, with or without the background, and different background, and expand or shrink as we like – so will need various graphic formats (.png, .ai, etc). The illustrations will follow the same colour system as our branding (details will be supplied) – the illustrations will be relatively simple illustrations – like the ones shown in the attachment. We would like you to finally put all the characters together to effectively illustrate what our software does and how it helps users – effectively tying up all the separate illustrations into one overall grand illustration. My budget is about $100. We will become the sole owner of all files, artwork, copyrights, etc. once payment is sent. I want to work with someone that will provide excellent customer service; this includes providing good communication and keeping me updated on the project, making revisions until every detail is perfect, etc. I also may have additional projects in the future for you if we like working together. Let me know what type of artistic skills you have. Providing examples of your work is helpful. I hope to end the bidding early and make my decision as soon as I have enough bids to make a decision. If you have any questions, then please ask. Thanks and happy bidding. BVagadia
