I Use English is an English company based in China, and they offer courses to third and fourth-grade students in group lessons of four to six children, but they have one-to-one courses too. They only look for native English teachers with teaching certificate. For the group lessons, the hourly rate is $12 USD with bonus. For 1-to-1 lessons, the rate is $4-6 per 30-minute class. They require a four year degree along with three years classroom teaching background. They welcome retired teachers. One thing you need to be aware is that you need to plan and prepare for the lessons. And two years of online teaching experience is required.
