Seeking eCommerce, Finance & Amazon Seller Expert Writers

I am building the blog for a client and need expert writers to contribute regularly. Right now the time commitment is ~ 1-2 posts a month and could grow. The client is a finance tool for eCommerce/Amazon Sellers. I need experts who can write the below example posts and also pitch their own ideas based on what is relevant and timely in the industry:

• eCommerce examples: "How to use revenue to fulfill future purchase orders" or "How to make selling on ecommerce marketplaces profitable"
• Finance examples: "Understanding the nuance of invoice financing" or "Financing inventory for every stage of your business"
• Amazon Seller examples: "Selling on Amazon vs Ebay" or "How to make selling on Amazon less scary for startups"
