Need my full Wix site converted to Fully Functioning Responsive HTML/CSS

General information for the website: www.thewaytheyare.com sells art by local artist
Num. of web pages/modules: 13
Description of every page/module: Full website conversion. I created this website on Wix (because it looks like one large java snippet) for my husband and it is very very slow (especially on mobile) which loses customers. I want to fully convert it to responsive HTML/CSS so that it views in all types of browsers, tablets, and mobile. I need the galleries and all the forms to work. I will be changing pictures text in the future so it has to be user friendly coding. It also needs to include the current SEO keywords and meta tags and picture tags. I am familiar with html and css but I don't have the time to learn the extra coding so I'm looking to pay someone to do this for me.
Description of requirements/features: Complete Website duplication in responsive html/css
