The fees aren't that bad, italki takes 15% of your lesson price which is a little more than I'd like, I think 10% would be more reasonable and also easier to calculate, but it's not crazy expensive. I became a tutor like 2 weeks ago and it's been going great!

Fees on Italki are very high. You might try Tusclasesparticulares.com

The other site takes no fees, from teacher or student. Counting the fees the student pays, Italki takes about 20 percent of each lesson.
