Konversion and Turbo Theme on Shopify

I am considering of paying RM 500 to scale up my Shopify shop using paid theme like Konversion or Turbo which is double the price at $350. ZelloShop.com is very well developed, has a hundred products and makes USD 100,000 per month revenue with USD 50,000 profit. I might just follow the excellent business model shared by 2 male business partners with 2 Virtual Assistants helping them for RM 4,000 in total. My Shopify shop is already 4 months in operation but still hardly any sales. Hence, I need a mentor to guide me to scale up my business to even greater heights. As you know, most of the succcessful Shopify owners are men, very few ladies are in this business, unless they sell maternity stuffs.
