There is no definitive answer to this question since it can vary depending on the individual or agency you hire, their level of expertise, and the scope of work involved. However, as a general guide, you can expect to pay anywhere from $500 to $5,000+ for someone to set up your Shopify store.
If you're on a tight budget, there are a few ways you can save on costs. For example, you can sign up for a Shopify free trial and use that time to set up your store yourself. Or, you can check out some of the many free or low-cost Shopify themes and apps that can help you get started.
Ultimately, the best way to know how much it will cost to hire someone to set up your Shopify store is to get quotes from a few different freelancers or agencies. This will give you a better idea of the range of prices you can expect to pay.
