Be very careful of using free vectors from sites like these. A lot of the work is stolen content from stock sites like Shutterstock and iStock or traced copyright designs. If you are making designs for clients I would not advise using any of those sites.
I don't know of a site that is specifically for commercial use, but there are a number of free vector sites which list specific licenses for each image. Many of them use creative commons license which makes it easy to know at a glance if the image you're viewing is available for commercial use.
Here are a few to get you started:
You can get free vector downloads via sites like http://vectorscout.com
Most of Wikimedia Commons is licensed under CC Share Alike 3.0. That means you can use it for commercial purposes.
There also a bunch of stuff that's released into the public domain.
Pixabay.com is a substantial and reliable resource for vector graphics. All of which are published under Creative Commons CC0 as public domain. So no attribution is required and the works may be used in commercial projects without restrictions.
