Website Design and SEO

Hello! I am looking for someone to help revamp my website ---------- It is a nutrition based website and I need to add more options for selling pre-made programs, know how to set up a monthly news letter, make the blog portion more appealing and searchable, index for recipes, promote my business in Google better as well as link podcasts etc.

Person has to be well versed in WIX as it is my platform and somewhat easy for me to use, as well as possibly be able to free lance in the future as my website adapts and changes.
