if youre looking for a way to list using csv files - once you have listed 100 items within a two month period, ebay will let you use their file echange for listing. can find more about it under seller tools on ebay http://pages.ebay.com/education/fileexchangetour/index.html
as for being able to publish 10+ items a night - if you create profiles on auctiva and use those with a template, will only take a couple mins per item for launching. Very fast and easy.
