Doom 3 modding/mapping

The cyber-game-club is willing to make a promotion single player map-pack for Doom 3. It must consist of 7-8 maps. We do not pretend to have as good maps as we can see in original DOOM3, but it must not look really amateur. We do not want to have custom models and textures. We just want playable extension with plenty of monsters and simple scenario. Scenario will be disclosed to accepted bidder. (It is simple enough).. I shall not read my mail during next week or something, so do not worry if I do not reply to your comments in fast manner during that period. Therefore I advise you to post as much info about your previuos experience as you can. Examples of previous mapping or 3D works will be greatly appreciated Teams as well as individuals are accepted. Deadlines and price are diccussible.
