How long does it take to create professional website design?
It is difficult to say. Can you share some details about your project? I need additional information. I think the best way to know development time and cost, is to contact with professional website designers company. They have big experience in ecommerce development and can provide big variety of different options for you.

Totally depends upon the features and type of website one need for their personal or professional use.
Usually website with totally custom features take time, but making website with a CMS is easiest way to have it in days.
It is interesting for me too
