modul matchmaking dating friendship

My planning for the upcomming year is to develop a matchmaking modul for drupal. I intend to have a community website, build on the existing modules from drupal.

I already tried some ready made modules, open- or closed source. There are some nice and proper solutions, but the opensource solutions seem a bit scary to me. The code was not really clear and problems may come up easily. The paid solutions appear fine too me, but very restrictive. Multilanguage will be supported like english, spanisch, french, german.
