What level are you? I can only recommend people who have been helpful for me at B2+ because that’s when I started using italki. I’ve tried a variety of tutors on there and some were not worth my money. Here are three that I think whose prices represent a good value for what you get:

Low price range: https://www.italki.com/en/teacher/14649851 We have similar interests so I can just talk to her about whatever. She’s not a professional teacher just a community tutor but she still corrects me regularly and gives good advice on how to say things. You choose what to talk about.

Medium price range: https://www.italki.com/en/teacher/7059978 Professional teacher so is more comfortable with making corrections to my speech. Another great conversation partner. Have to provide your own conversation topic.

Higher price range: https://www.italki.com/en/teacher/5590189 Only have had one conversation with her but she is a professional teacher and provides prompts for you to talk about (this is worth the money for me, as it allowed her to find my weak points relatively quickly, instead of allowing me to stay in my comfort zone).
