Custom options for Wix Art Store?

I have a client that makes Acrylic Facemount pictures on canvas, I wanted to see if anyone knew the best way to help this Wix client? Here’s what needs to happen: When someone comes to the site and picks a selection it needs to then allow them to pick a size, pay and submit order to vendor. Her company is the vendor so I don’t want to use Order a Print. I’ve spoken with support and they’ve giving me their options but I’d really appreciate your solutions or coding options. Thanks!

This sounds like what we like to call “mega stores”, which has a lot of coding options. Hopefully some code experts will chime in :slight_smile:
