We spend about $1,500 to $2,000 a month on Google Adwords. I believe we can improve the effectiveness of our PPC campaigns to achieve higher conversion. Since we are a small potato, we don't want to pay a company a lot of money each and every month to help us tune up our adwords campaigns. Does anyone know a great freelance PPC specialist that can help us be more effective as a short-term consultant (can be worked into a more long-term gig)?
