Online Store Setup and Management

I’m looking for a trustworthy freelancer to help me launch an online store on eBay, Etsy, or Shopify as soon as possible. The goal is to start with a very low budget and grow over time. This is a revenue-sharing opportunity, so I’m looking for someone reliable, proactive, and committed to helping the business succeed. Experience with online store setup, product listing, and ongoing store management is important. Please share examples of similar projects and your approach to low-budget growth.
