Joomla data transfer

JOOMLA EXPERIENCE REQUIRED. COMMUNITY BUILDER EXPERIECE PREFERRED. I won't reply or accept generic automated "We can do this job sir" emails and bids. You must have sample of joomla work. I have an existing adult dating site using the MamboMatch component installed on Mambo with approx 300 members. I need someone who can convert most of the profile data, including username and passwords, and profile photo (one photo) to community builder -by creating the appropriate/corresponding data fields in CB on the new Joomla install. The username and password have to be imported to CB so that users don't have to re-register. I have already installed Joomla and community builder on another hosting account.
