How to create a seller showcase for a niche community on my site?

[EarpBands]

I run a business selling products in a small specific community. Within this community there are many other artists / creators who also create and sell incredible things. 

As part of my Shopify site I want to create a 'Seller Showcase / Marketplace' where I can list various different sellers within the community, link their social media and external sites to Etsy, RedBubble etc.

Kind of like the holy grail of merch within our community.

I've been using PageFly to create something basic along these lines, but I want visitors to be able to filter by items that shop sells, where they sell etc. 

Is there any app that could help me do that?

One solutions would be to create a custom collection page.

Thank you for responding. This would only work with existing products. I want to have individual artists with links to their social media and online stores I am currently working on this in PageFly but it's all manual and there is not ability to filter sellers by what they sell.
