New website SEO help needed

Our company is an online tour operator, packaging and selling winter sports holidays for UK based customers. We started trading at the beginning of October this year. We are looking for someone to set up the SEO on our website (wordpress, using a yoast SEO plugin) as we ourselves have little to no knowledge of how to do this. In addition we would like to run though how to increase our quality score and ranking on Google AdWords through our websites organic SEO. Our site currently consists of 23 pages and a handful of articles so it should be fairly straight forward for someone with experience in the field. Thanks
