Multi Store Opencart under same domain and hosting

Hi, I looking for some one who have a very good knowledge and experience with opencart and how can build Multi Store by Opencart under one domain and one hosting, so one of the store will be for the USED section and other one will be for the NEW section. And I like to add for each item the "Item condition: (NEW - USED - Refurbished)" Like [login to view URL] *** Plz find the attached fine to understand my point *** I can do it but i don't have time.
