Connect ADS database into SQL Business contact manager

hi, we have a current address system for the whole factoring process, but it is not so good for marketing and sales efforts. Therefor I would like to switch to Outlook business contact manager. But in the other system we do have a database, which is an ADS database using tables like .adt, .adi, .adm etc. This database can be connected to an SQL database via ODBC. In Outlook BCM there is already a SQL database integrated. The question is, if there is a chance to connect the ADS database via ODBC with the Outlook SQL database? We need a reliable freelancer, pls let me know the capital of the country Germany when you reply.
