I don't know if you received any direct responses or not, but since you are new let me offer some advice.
1. Set your profile to allow messages from anyone, not just friends.
2. Add an introduction to your profile telling readers a little about yourself and your interests.
3. Set your English level in your profile so people have some idea what to expect.
4. Offer to help those studying your native language in exchange for English.
5. Keep reading the community section of italki for more advice and opportunities to practice.
6. Search the language partners section of italki.
It can be a challenge to find good partners but don't give up!
