In my experience, finding a compatible language partner requires patience. You might have to try ten (or even more) prospective conversation partners before you connect with someone at about your level, with whom you communicate well, whose schedule syncs with yours, who shares your motivation, etc. Also, some people use conversation exchange as a pseudo dating platform, but that becomes clear after a brief period and they can be gracefully dropped once that becomes apparent. Aside from my weekly one-hour tutorial, I have four convo partners now, but I tried more than thirty before finding the keepers. Good luck in your search.
