Need help integrating WordPress with RealChat

I have a client who has asked me to install RealChat on his site, and he’d like to require users to be logged into his site (it’s a WordPress-driven blog–people already have to login to leave a comment) before they can chat.

As far as I can tell, RealChat supports this just fine:

However, I’m not a programmer and only understand the most rudimentary parts of PHP–so I’m not in a position to make this work.

Any explanations would be helpful–I’d also be more than willing to pay a developer who might be able to quickly get this up and running. Let me know if interested.
