"Adult" or any "pay to get in" sites will cost quite a bit. That $1,800-2,500 quoted price is most likely just for the design/content management system. Servers will be around $200+/month.
You may be able to setup something such as Joomla and then pay someone to theme/mod it. But once again, with that you'll be pushing $800-1,200 for the "basic" things. That also doesn't include the web server(you can't use basic/shared hosting for adult, or pay-to-get-in sites - atleast most good hosts won't allow it).
