Google Ads Campaign for Shopify Store

I’m seeking a Google Ads expert to fully set up a new campaign for my Shopify website, hundevennen.no. Currently, I have a PMAX campaign that isn’t yielding optimal results. The primary goal of this new campaign is to increase sales, focusing on my best-selling products. The target market is national, so I need a professional who understands how to strategize for a national audience. Experience with Shopify and Google Ads is essential, and a proven track record of increasing sales through successful campaigns is a plus. Please include your price for this project in your proposal.
