Transfer Osdate database to Wordperfect

I run a registered volunteer-only U.S. non-profit that supports a marginalized community. We have a members-only website online for 8 years for this community to connect with one another privately. I'm using an older version of OSDate (2008). We don't use it as a "dating" site. There are over 4000 members, with up to 5 pics each, and extended bios. (No videos). I need to move these members, bios and pics to a private Wordpress site where members and content can only be seen by members. (I will have the Wordpress site ready using Buddypress with Members Only plugin and all you have to do is import from the OSDate database.) I have a very limited budget - so any bids over $75 won't be chosen..
