Hey guys, I'am brand new to Shopify and setting up a website so please bear with me. Just this week i registered my domain and started building my website on a user friendly website builder. I have just realized what i need it to do in respects to my store, they do not offer. My goal is to set my website up where users can buy and sale without me having to post the items. Basically, when a customer checks out, my commission comes out, the seller gets their money and shows them where to send the product. i'am also wanting to add an auction page where customers can view, sell, and buy items that the seller chose to auction off instead of buy out right. I understand Shopify is capable of this, i just have no idea where to start to get this accomplished. And since i already have my website partially built, am i able to just transfer these actions to the site or do i need to migrate it to Shopify?
Thank you so much to anyone that is able to help me steering me in the right direction!
