Hi Francisco, welcome to UltimateWB!
For social networking apps, including the Classifieds app, you would need the UltimateWB Full software. The software itself is $249, one-time payment that includes 1 year free software updates. We provide free tech support via email and on our forums. We do also have web design packages available at https://www.ultimatewb.com/pro-services#webdesign . The packages are quoted based on the number of pages you need. You can get more info on the web design packages at https://www.ultimatewb.com/web-design-packages-info . You can choose to create some of the pages yourself, and have others created for you, depending on your budget.
You can find examples of social networking websites built on UltimateWB on our Showcase page at https://www.ultimatewb.com/showcase .
You can also check out what our customers say on the Testimonials page at https://www.ultimatewb.com/testimonials-software-reviews (includes video recommendations too).
The software / services can be purchased under the "Purchased & Download" tab on our website. Here are the direct links:
1) Software Purchase: https://www.ultimatewb.com/buy
2) Web Hosting / Domain Name Purchase: https://www.ultimatewb.com/domain-names-web-hosting
You can choose to host with UltimateWB or with another web hosting company that satisfies the server requirements as listed at https://www.ultimatewb.com/server-requirements . We do provide free software installation for all of our web hosting packages (still requires separate purchase of the software though). You can also choose to buy your domain name at another company, or use a domain name that you already have registered, provided that you own the domain name and are allowed to set its nameservers. We can help you with this setup, as should the domain registration company.
Besides, web hosting, an option is to purchase the SSL add-on for securing private data transfer on your website. You can find more info on this here: https://www.ultimatewb.com/domain-names-web-hosting#ssl

Besides free tech support via email and on the forums, we have several resources online to help you build your website, under the "Resources" tab on our website.
