I am always encouraging my customers to start a Google AdWords campaign. You can start relatively small budget and, in addition to generating additional traffic and sales, you can gain some fantastic marketing data in the process.

If you would like help getting started, I can help you get set up, configure your campaign, create ad copy and optimize to help you get the most from your ad dollar. AdWords is a pay per click model, so you only pay when your ad is clicked …and to help out, Google has just sent me a stack of $100 coupons to help businesses open accounts and get started!
