Simple website design and content maker for marketing

I'm looking to hire a freelancer to design and create a website for me from scratch. The website will be powered by WordPress and must be mobile friendly. I already have a domain name registered and need content creation to be included in the job. This website will be used for my business and is expected to be a core component of our marketing strategy. I'm looking for someone who is knowledgeable about website design, content creation and SEO who can help me to create a successful website.
