Take a look at our basic version of Elevated X -
http://www.elevatedx.com/basic/ - It's a single site license with hosting included starting at only $49/month. You can upgrade seamlessly to the full Pro CMS anytime you're ready to build more sites.
We've been powering hundreds of solo model and pornstar sites, big and small for the last 10 years. I'll be happy to go over the pros and cons of different site and CMS setups with you regardless of whether or not Elevated X is the best fit for your needs.
Feel free to contact me direct with CMS or just general pay site related questions.
