Marissa25 There is no exact answer. The time and cost to finish your website redesign greatly depends on a lot of factors: functionality, complexity of the web design, hosting and also, developer rates. But on average it will be charged $15,000 to $30,000 for a simple ecommerce website. For a medium-sized ecommerce website, you will be charged with $40,000 to $80,000. For an enterprise ecommerce website with more custom design features, you will be charged $80,000 or more.
But this information is very approximate, as the redesign cost is very flexible and depends on the type of site you want to develop.
