Our
Vantage directory theme will allow users to post a listing based on your specified pricing option and others to view without payment, so you may like to check that theme out for your first example.
There is not so much of an exact match in terms of your second example, as none of our themes have a checkout functionality built into them. There are .csv importers in our themes, but not exporting tools, you'd need to use the WordPress export feature for exporting. The closest you could get to the shopping cart side would be the
ClassiPress theme in conjunction with one of the available ClassiPress child themes which include woocommerce compatibility
here in the AppThemes marketplace. Thanks.
