You can have a free talk with me here in Italki.

Hi Floy! Let me help you with that. You can see me here on Italki.

thank you for you advice, if you want some help on Chinese, you can also add me as a friend and when you are free, we could have a communication😊

but this way also has a limitation, should I wait until it was fixed? Or just because there is a time limitation, like I can only talk to someone in few hours?

Add him as a friend, then you can exchange Skype information. I am currently working on a paper for school, otherwise, I would talk to you. I work online for a private Chinese English company.I am a native speaker.
