linking 2 scripts together

We have a site built from the Dolphin CMS (mysql and php), we recently had someone install ilance but they didn't join the databases like they were paid to do. What we need is to have the dolphin members to become instant ilance members. At present dolphin is running off one database and ilance is running from another both at the same server and both being mysql. please only bid if: you can definitely do this, as iLance is very secure. and 2 you can do this soon, this is the 3rd time that i have post this job. I really need this done quickly.
