Marketing/SEO Specialist

I work in wholesaling real Estate. I need someone to serve as a marketing specialist for my company and website. They need to make sure my website is fully optimized through SEO. I want my site to be at the top of the google and bing search results. I also need someone who is good with marketing to include social media, Craigslist, Facebook market place, and various other platforms. Another part of this job is to handle leads and keep track of them using excel and the software PropStream. I may also ask you to make cold calls to potential sellers.
