If you are looking for an e-commerce website and you want to go with a big Web Designing company in that kind of case my suggestion is don’t go with a very big company. Any big Web Design or Development company charges you a lot for an e-commerce website. Ecommerce website is costly because of too much complex coding in there but a company charge you a lot of extra money more than a freelancer. If you don’t want to waste your money then my suggestion is don’t go to an e-commerce website development company at first discuss with me. I will try my level best to give you a suggestion.
