Cartoon character design for web site

We require three simplistic cartoon characters for our web site and promotional material. Each will embody one of the three aspects of our web site. We will initially require two poses for each character, but will gladly hire the winning bidder for further work at a later stage. We might also require a new logo, depending on whether the characters "fit" with the existing logo. Please bid for the character designs only. We will pay extra for the logo if necessary. Please use Private Message (PM) to provide links to your portfolio and any other information you feel we might need. Serious bids only, please. We will shortlist our favorite candidates (based on your portfolio), and provide more details, so you can pitch some rough ideas. Therefore, if you don't have a portfolio, please don't bother placing a bid as we will have to ignore it. Work will need to be original. No stock pictures, please. We will require ownership of any designs that we pay for. Payment upon completion of original 3 characters x 2 poses each. Further work will be paid for as required. Happy bidding.
