Build a website own Wix

I have a Wix website that I have cobbled together myself. It needs to look more professional and I need to be able too update some photos myself. The basic desktop and mobile site I need is:

• Home page with logo and intro blurb – links to socials (insta/twitter)
• Bottom red banner would have two buttons:
Terms & Conditions of Sale
Terms & Conditions of Supply
And our address and copyright
• Menu would have
Contact form
Gallery – places for me to upload some covers with blurb

We are a children's book publishing company and so can supply lots of images in any format required. Please see current site I put together www.townhouse-books.com.
Thanks
