google adwords manage

I am looking for an experienced AdWords specialist to help manage my monthly advertising campaigns. I have a budget of less than $500 and require help with both text and display ads. My focus is on local customers, so my ad campaigns will not need to target people located in different countries. The successful candidate will have experience creating and managing effective campaigns that are within budget and reach the right potential customers. My expectations are a positive return on my investment within the specified budget.
