I am always looking for social network sites to build for my clients to reach their markets and I search Google for companies who produce the software, but the best software right now is Chameleon. Not only does this software handle social networks, but also dating sites.
For those business owners who want a demo, the Demo page at http://chameleon.startsocialnetwork.com/demo.htm is available.
What’s even better about Chameleon is that they offer both single site and multiple site licenses, so if you want to build many sites with different themes or markets, Chameleon has you covered for sure.
