Tell me please, how expensive it is now to create a full-fledged website for an online store with a full service cycle.

The price for the creation of the site will depend on your desire to design the site and its options. Definitely it will hardly be possible to answer your question. If we talk about the quality component of the site would recommend you to create a site in accordance with this model as peer to peer marketplace platform . Such a site will be able to fully provide a full cycle of customer service from order to receipt of goods. Also, all financial issues will be convenient to conduct in such a platform. LightIT has enough experience to create such a platform.
