Boosting Sales with Google Ads

I am looking to start a Google Ads campaign with the primary purpose of driving sales of products and also lessons and rentals for my company. We operate in the watersports industry, but it's not clear yet which of our services or products will be the focus of this campaign. It's important to note that we're still defining our target audience. I am looking for a freelancer with a strong background in Google Ads creation and optimization who can advise on the best strategies for achieving the objectives, considering these uncertainties. Understanding of the watersports industry would be beneficial.
