Now that you've created your keywords, broken them down into campaigns and ad groups and written your ad copy, you have to put it all together. At this stage of the game you should either have one spreadsheet with all your campaign elements that looks something like this:

The color coding is just to make the various campaign elements more visible, but essentially we have three columns
Here's a shot of the same spreadsheet with the ad copy included:

You have two spreadsheets (or one spreadsheet with two worksheets) - one that lists the campaigns/ad groups/keywords and one that lists the campaigns/ad groups/ad copy. I've uploaded samples of campaign development worksheets in the Tools section.
You should now download the Adwords Editor if you haven't already and begin posting the campaigns into the editor. The editor comes with ample instructions, but I've created a cheat sheet which is located int he Tools Section as a quick reference guide. If this is something you don't have the time or technical expertise to work with, then you may want to consider calling me for a training session. It's a lot easier (and quicker) to show you this stuff than to have you wade through all the instructions.
