Website Design

We have a website presently on Wix. Www.hoplex.net which was made in house. We require a more professional looking website, which is clear and simple to navigate with a fresh looking design, suitable for an engineering company. I would prefer that it be done in a way that I can edit text on the website in the future, or some other platform that I can edit myself in the future to change text, add new products etc. It need not be Wix.

Thanks
