Englsh Teacher needed, with background in small business

My wife is looking for a teacher of English with a business and/or marketing background. She currently can communicate with every day English, I think a level B1. She has a huge vocabulary but needs direction and order. She has had no proper training. She is looking for someone that can provide a concrete guide with great direction to advance in good order and with the theme of small business, marketing, social media marketing, or basic finance. Her objective is to start a boutique company as an entrepenuer and undestand what are the basics required to operate a small online business and store front. A step by step guide on the basics of starting a small business is preferred as a theme for learning English.
