Website idea, is it realizable with drupal?

Hi there, i recently had an idea about a website i could make, and since i already know a bit of Drupal, i was wondering if there actually are the tools to make this happen.
Basicly it's an e-commerce website, but i want users to be able to create an account and add their own objects to sell. An used stuff website which links buyers and sellers.
Clearly after adding the object, drupal can organize stuff and let other look for it easily.
My doubts are on the first part of the website. I have looked for some modules, but all i found were modules about classic e-commerce.
Can you tell me if it is possible with Drupal?

Thanks in advance, Mario.
