Cheaper speaking practice than iTalki?

I've been thinking that I want to increase my amount of output, and just practice speaking Japanese more often.

I speak Japanese at work, but it is always about the same topics, so I don't get a lot of variety of practice. Then when I find myself hanging out with Japanese people, I can barely participate in conversations.

I thought I'd just go on iTalki and find the cheapest conversation partners possible and just book one person for one hour every weekday.

Thing is, the vast majority of teachers, even the cheapest teachers, on iTalki are charging about 2,000 yen for 60 minutes. That's 1万円 a week. 4万円 a month. A little more than I was hoping to pay.

Thing is I'm not even necessarily looking for teachers here. I'm just looking for conversation partners.

Does anyone have any recommendations for alternative platforms or alternative ideas for how to get speaking practice in?

I've got a full-time job and two kids under five so I can't really just go to a bar every night and chat up the locals or anything like that.
