Web Site maintenance and SEO

I have a web site and web store built in Wordpress, hosted by Hostgator with a Shoppe pluggin.

I need a design/SEO specialist to maintain the site for me on a monthly basis and add pages, modify content etc on a regular monthly basis.

I run Google adwords/shopping campaigns which will also need to be developed and refined.

As the site starts to generate revenue I anticipate expanding into other markets with new sites.

I need a reliable person that can work with me long term and grow with my business.
