Google Shopping Help

I have Google Shopping setup on one website. Some products arent approved. Need to make sure as many possible products that can be approved are approved. Also, might try some paid ads for a few products. And if you are really good with Google Shopping then I will get you to set it up on another 2 or 3 websites. You need to be vastly experienced with Google Shopping and be able to provide work history with examples and cases of success stories.
