To my understanding, mormon.org and "email missionaries" work generally out of the MTC - to field requests and have basic conversations. "Email missionaries" are not the primary means of teaching the gospel, but having basic conversations... probably not quite as in-depth as we've had here with you on LDS.net.
What needs to happen is for your request to be forwarded from the MTC, to your local mission president's office, who will forward the request to the appropriate set of missionaries in your area.
It takes a little bit of time to coordinate between departments.
If you want to hurry the process along... you could call your local meeting house. Someone will answer the phone and help you get in contact with the local missionaires.

This is not unheard of. When I served my mission in Tennessee, we had a lady call up the Church building and asked to have a visit from the missionaries. They called us up and relayed the information. We called her and set a time to meet. She was baptized within 3 weeks.
