330669 linking joomla with vb forum

Dear everyone, I have vb forum and joomla 1 linked together by jvbPlugin. I want to install joomla 1.5 and cancel the link between joomla 1 with vb forum, and make the vb forum linked with the joomla 1.5 by jvbPlugin ( not migration ). And yes their is custom docman in joomla 1 I want to move it to joomla 1.5. That's all what I need, but I want somebody who can make the job fast ( maximum 48 hours ) and perfect. Note: my site, joomla and the forum are Arabic, so I don't want the Arabic language change to symbols. Best Regards, Sarab
