Only those with relevant access to the back end
wp-admin would be able to post an actual blog entry, and there is no functionality to charge for this within Vantage, so it would require customization of the default theme on your part if you wanted to allow this. This being said, if you can make those modifications anyway, then it would probably be easier to just customize the built in listing functionality. You can already add website URL's there too. AppThemes does not offer customization services, however we do have a
certified partners page where you can find developers for hire. If you make contact directly with an outline of your requirements, they will be able to provide a quote for the work. Thanks.
