Podcasting Advice Request

I have been a podcast host of a very small, niche show for a couple of years. Although small, I have a loyal following that seems to really enjoy the content.

I pay a producer to post the show each episode. I hear ads play on the show, so I suspect that he is collecting something from advertisers. (Or maybe not…they could be ads from the hosting platform that he uses.) Nonetheless, it is costing me money instead of making me money. I realize that I am not going to get rich, but if there is an opportunity to make money, instead of cost money, clearly I would rather do that. And if I am paying his fee, I may as well pay a platform and have the opportunity to recoup some of those costs.

I have considered trying to post it myself in the future.

So…. I have seen multiple podcasts services online. Which service does everyone use? Ideally, I would like one that allows me to post on multiple sites, as well as potentially hosts several podcast under that same membership fee. What are the pitfalls of venturing out on my own? Is it so easy, a caveman can do it? I feel 100% confident behind a microphone, but struggling with the concept of posting it. Any advice would be appreciated!
