I've run a few podcasts over the past 8 or so years. Had a lot of fun, a moderate amount of what I consider success and a lot of chances to make mistakes and learn. This is probably going to sound negative, but I only want to pass along the reality of what I've learned.
As Bulgakov said, you definitely need to decide what kind of podcast you're creating early on and define what it is and how it runs. Be very realistic about the time investment. Be very realistic about your continued interest level and those of your partners. The number of podcasts that stall out after 3-5 episodes is staggering. STAGGERING. The cadence is something like this: First episode comes out, second episode comes out, third episode comes out late, fourth episode comes out even later, possibly with a co-host change. Fifth episode comes out months later, never to be heard from again. No judgement, I've done almost the same thing at one point.
Video Death Loop, my show, is about as lean of a podcast creating machine as you can imagine. Two hosts, both well versed in audio production and at this point, the show itself. The show is off-the-cuff, almost no pre-planning needed. Post-production episode templates worked out long ago. We do a 30-45 minute show once a week. It probably takes 4 man hours for recording and editing. About an hour for pre-show testing/recording and about 60-90 minutes per person for post-production like editing, updating the feed and then running social media. I honestly don't know how anyone could generate a show in fewer man hours. You can probably use that as a bare minimum baseline for likely time spent.
Guests make shows exponentially harder to plan and record. Adding multiple guests creates a nearly never-ending maze of scheduling conflicts. Clout or money can ease this burden a bit but at this point you likely have neither.
Audio is hard and different. You can't fix systemic quality issues in post. If your recording sounds like trash, your podcast will sound like trash. It's worth it to find some good equipment. Here's
episode 1 of my podcast, recorded on a Blue Yeti in a shitty room, here's
the most current episode recorded with a proper audio setup including bass traps, audio foam, proper mixers with amps and Shure microphones. I probably spent more in post time trying to get episode 1 sounding even remotely listenable than I did the current episode which sounds extraordinarily better, because I started with better audio on the current ep. Better eps and less time spent editing? Spend the extra money up front if you're sure you want to do this. (It can be less than you think. I think my current gear setup was probably like $300 all told, not including the computer obviously.)
Ultimately remember that the most unchangeable part of your podcast is its RSS feed. Whether people are subbing through one of the seemingly hundreds of podcast catalogs that will scrape and list your show or directly on the feed itself, that's where all roads lead to and from. Choose a service that will be around for as long as you want your show available.
Have a lot of fun, but do remember what you're getting into. Building an audience is not anywhere close to guaranteed. Be sure you enjoy and are passionate about what you want to do.
