If you have never used adwords, then a simple campaign with 10 keywords should take less then an hour.

If you have some Adwords experience, this would take less then 5 minutes.

bdm is about right, I'd take 5 minutes for that. But 10 Keywords? This is either one VERY specific niche, or you're doing it wrong. A quick comment on Quality Score: QS is Google's perception of the relevance of your site, ad, and keyword to the user's search query. They want more relevant ads so their users don't get annoyed or see ads as spam. QS, along with advertiser competition, determines the price you pay per click, and the difference in terms of price can be staggering. For example, if you query "blue cars in boston with no rust," and my Adwords keyword is "cars" I'd be paying $10-$15 per click. If I happen to have "blue cars in boston with no rust" as an Adwords keyword, I'd be paying 15-30 cents. A campaign with more specific keywords is cheaper per click, AND more relevant to the searcher which means they'll be more likely to convert.

A pay-per-click advertising system from Google. Companies and websites can purchase AdWords and have their own ads appear contextually together with search results.
