I have two of my own brands; started with less than $5k, importing products from all over Asia. I take more interest and pride in developing long term products, brands and businesses ie. not fidget spinners or other fads.
I run every aspect of my Amazon business myself so I can help with: PPC, Sponsored brands, AMS ads, Product Research, Strategies, Shipping, Listing Design and standing out from competitors. Models for analyzing cost correctly before you order. Getting more reviews, more revenue etc.
