[Wanted] PHP/MYSQL Programmer For Member Synch Script

Greetings.

I have a site with Mambo CMS, and am also running external apps. We've had a problem with users signing up for multiple accounts, and this just makes the database unnecessarily bloated.

What I need is to have the user tables for Mambo synched with an external application (in this case, eFiction, which is available for download here).

The idea here is for the applications to still be able to function independently of each other and basically share member data.
Ideally, the solution will:

• Synchronize member data across both applications (i.e., if a person joins Mambo, (s)he is automatically written to the application's user data), and vice versa
• Sychronize logins (i.e., if the user is logged into Mambo, then (s)he can click on the app and be logged in there). I've seen many scripts that allow for this. Only having the username and password shared is sufficient. The user can put in his/her own profile information within the application itself. This hopefully will keep complexity down.

I do not expect full integration with the CMS! Since these are separate applications, they should remain standalone, only able to share user information.

It'd be especially nice if the solution were an independent script/application that could be called to do the synch. I don't want the source code for any application altered (this prevents complications later on).

Please PM me with your questions and offers (including estimated time and price).

Thank you in advance for your responses.
