Hi Bryan,
Thanks for posting! You can build a classifieds website with the built-in Classifieds app in UltimateWB Full software. The software does not come with design templates, but rather a Styles Manager to create your own template. You can read about how the Classifieds app works in the User Manual here: https://www.ultimatewb.com/classifieds-app/create-customize-integrate-classifieds-section . We have demos of the software available at https://www.ultimatewb.com/demolinks . You can also find video tutorials at https://www.ultimatewb.com/video-tutorials .
The costs involved would be:
UltimateWB Full software: $249 (one-time payment, comes with 1 year free software updates, with option to get a renewal updates package). All UltimateWB web hosting packages come with free software install service of your purchased software onto your web hosting account.
