Is there any ready-made solutions platform marketplace (aggregator of goods)?

Expect in the near future start creating a marketplace platform for B2B and B2C 1-3 million products. At the moment, has already built a similar business but on a more modest scale (5 suppliers and 50,000 items), were taken as a basis a CMS for online store and modified it for their needs, the business is successful and brings a steady income and plan to "pull." I want to know is there any ready-made solutions marketplace platforms, simply put commodity aggregators, in order not to reinvent the wheel, and take existing strengths and to adapt them for yourself.
