Auction Sites - Are they any good?

How to drive traffic on an auction site. To start with I have chosen a niche - only baby products. Is it worth investing in and what channels do I use to drive traffic? Would people post stuff for a fixed fee for posting or would it be better option to get a cut of the sale that happens. It;s a new site, so the sale option might be a bad thing for me as I'm yet to start getting traffic.

Kindly advice. Thanks in advance.

hire a virtual assistant from a good provider and build backlink to your sites, go to some forums to post. Combine both On page and off page Seo.
