Google Ads Performance Audit

Hi, we're looking for a Google ads specialist to do an audit on our Google ads account to identify ways to improve performance with the setup and current performance. The person needs to be a specialist in auditing Google PPC ad accounts. We're looking for an initial audit piece of work (ideally around 3-5 hours) to identify the biggest wins/problems via a simple audit document with an accompanying video if it would be helpful. Following this, we would need ongoing monthly support from this individual.
