Hi there,
I'm experienced with WIX and recently i have also developed an E-commerce website for a client and his requirements was also something similar, He wanted me to make dynamics pages, connect page reviews to the database and add custom filters for product sorting in the page.I have been working with WIX for 3 years. I am good with JavaScript which is used for coding in Wix corvid.
So i believe i can serve your purpose if you feel the same contact me.
Thank you for your time.
