Hello Bryn - pleased to meet you!
You're right - it can be a lot of work getting started. If it's something you love to do, and you've got the drive, keep at it.
As for a home studio, you can start small. Even a nice USB mike connected to your computer can be helpful when learning. Recording articles, ad copy, etc, then listening back is a nice addition to classes and coaching.
Do you do Stage or Improv work? Both are good for honing your speaking skills, and you may even develop a couple characters or accents along the way.
Plenty of helpful, experienced folks here when you've got questions. Many have been answered in the past, so don't forget to do a search also...
Hope to hear much more in the future - Welcome!
