Our theme purchases do not include installation, so essentially you'll need to be able to install WordPress on your hosting account in order to then install and activate ClassiPress. We do offer documentation relating to both of these
here, and the support we offer is via the forums. Whilst we don't offer installation or customization services, we do have a
certified partners page where you can find developers for hire, if you are looking for help for those aspects of the setup. Thanks.
