Adwords - Build Keyword List

Hi, We need an extensive keyword list building for a Google Adwords campaign. The topic is ebay/make money related. We already have an fairly extensive list from a previous campaign which can be used as a base to build further keywords. We'll send over a couple of hundred tested, proven words, which you can then build on through Keyword generation tools (we'll supply the tools too). Output the results to Excel. Also add any further keywords of your own, through whichever software you wish. It's quite a 'manual' task which may take a week or so. I'm quite flexible with the price.
