Structure/building design for Medieval War Game

Warlords Dissent is a browser-based medieval war game which focuses on the use of strategy, politics, military dominance, economical power and espionage. In Warlords Dissent, players compete against each other to raise their settlements and dominate the content with their Tribes and Kingdoms. We are currently seeking a professional and talented graphic designer to design approximately 30 structures for the game. These structures are set in a medieval time and we required three designs for each structure: (1) A 128x128 px isometric object depicting the structure (this should be placeable on a map, e.g. [login to view URL]) (2) A 128x128 px illustration depicting the structure (will be the above structure placed on top of an appropriate background with some additional design elements to make the image fit in a war-related theme) (3) A 64x64 px icon depicting the structure (to be used as a mini-icon for representing the structure) This is a very simple and easy design project but we are looking for quality work so we will only be accepting bids from individuals who can present samples of related work that they have undertaken previously. Thank you.
