Edit existing Wix Website & Create new Wix website

I have an existing architectural website (www.Ronansweeneydesign.com). I need to completely revise this existing website to be more professional looking. I have lots more content to upload onto it. I have some ideas as to what it should be like but very much open to your own creative ideas.

I am also starting a new company website that offers 3D visualisations from 2D drawings.
I have the content to upload and can point you to similar examples.

I already have an account with Wix. If you need any more information please let me know.
