Firstly, I would suggest you to list your products on products listing sites( free & Paid). Google products feed is free of cost so initially you should list your products on Google Merchant that will not only generate the traffic for site but also some genuine leads for you.
Secondly, I would suggest you to do aggressive classified listings, articles posting, blog commenting, forum discussions etc.
Finally, I would suggest you to create social profiles on all major social networking sites like facebook, Google+, Linkedin, twitter etc. and participate actively to create brand awareness.
