Learn Catalan Online PLEASE HELP!!!!!!!?

I have looked a lot the past few months to find a website or an university that teaches online Catalan classes. I don't find the random websites that offer grammar tips or a few phrases for aspiring travelers to be very helpful :( I am aware of livemocha.com and I have begun using that but I was wondering if anyone has found actual classes that you can take online to learn Catalan. I am moving back to Spain in the fall and I would like to be as fluent as possible in Catalan because it's very important to my new job I just got...Please anyone can you please give me any sort of advice or websites. I would appreciate it so much...
