Optimize Google AdWords

Hello, my business operates in the services industry and I am looking for someone to help me optimize my Google AdWords budget. I currently have a budget of less than $500 and my main goal is to increase the click-through rate. I am looking for an experienced freelancer with knowledge and a portfolio of successful projects in this area to deliver results. If you believe you have what it takes to improve my adwords campaigns, I would like to hear from you.
Thanks!
