Which CMS to use for Online Marketplace

I've come up with what I think will be an awesome idea for an online marketpalce. I'm just a bit stumped on where to start, like which CMS to build it off.

So far I've realized that I will need to create a simple MVP (Minimum Viable Platform) and although I have experience using WordPress, I'm wondering if there are any better CMS's that I could use. I find Wordpress is a bit slow and is more suited to content instead of e-commerce.

A quick rundown of my idea is:

1. Person A posts an advert of a physical Item they want to buy. In this step, I charge a commission for them to post the advert.
2. Person B accepts the job and buys the physical item.
3. Person B Delivers the physical item to Person A.
4. After a successful transaction, both parties leave a review of the transaction (similar to Fiverr or Ebay).

Ultimately the only transactions that will be processed on the site will the be the commission I charge Person A to post the advert. I imagine it could work similar to a classifieds site like Craigslist or Gumtree, but with the added user ratings and reviews like Fiverr or Ebay.

I've thought of using something like Magento or Drupal, but because of the learning curve and investment needed, I'm wondering if I could start this with something a bit more simple.

Any Ideas would be appreciated.
