If you're looking to practice English and need something to work on for free/cheap, look up the textbook series Side by Side by Molinsky and Bliss. I've used it to create conversational English classes for Chinese university students. It carefully drills you on correct conversational grammar, introduces you to vocabulary, and doesn't force you to learn grammar rules. It's got grammar behind it all but it doesn't make you focus on that. Then, when you're ready to start taking lessons on italki, you'll get more because you have worked out a lot of the basic issues on your own and you'll get more from each lesson.
