Design Needed

I'm just in a middle of web page redesign and are in need of a new graphics. This website is related to internet domains (registration, resources, auction,marketplace, information) and we are looking for multiple pictures from multiple contributors. These are specifications: 1. All graphics needs to be 400px x 200px. 2. All graphics needs to be created using Adobe Photoshop or Fireworks and provided in png/psd extensions. Also actual graphic need to include multiple layers. 3. I'm looking for 4 graphics at minimum and these are teams: Domain registration, domain auction, domain marketplace, domain resource/information guide. Any additional graphic you provide will be taken as a plus. During bidding what to consider: 1. Work needs to be unique – if we think in any way submitter has "borrowed" any part of his graphic we will not consider this bidder. 2. Quality – be unique, imaginative and surprise me with your ideas. I'm not looking for average work. 3. Quantity – I'm looking for +4 graphics described above so if you submit more you will have a higher chance to be chosen. However being unique and quality is much more important. Bidding: Together with your bid please attach at minimum 4 graphics in jpg/gif or some other extension so we can preview your work. If I like your ideas I will let you know and transfer 50% of payment to your account. Once you provide me with original files I will transfer the rest of money. Auction duration is 30 days just because I'm are giving everyone enough time to complete their work. Please do not bid without attached preview as I will not consider this bid as valid. Again, website is related to domain (guide, registration, auction, marketplace, information,...) and we will be choosing multiple winners. Please let me know if I need to provide any addition info.
