I've read all of the replies to you initial question.
I was in the same situation as you 23 years ago when I too decided to do catering, but chose to strictly go corporate so that I can enjoy the rest of my life raising a young family. It was a wise and rewarding decision.
Catering is not as difficult as most people think, as long as you know what you're doing and stand by your products and services.
Once you read the books, and are more familiar with the trade, you'll get a better feel for it.
Don't forget......this forum is here to help you, not deter you!
DON'T RISK ANYTHING BY DOING IT AT HOME!!!! You can end up losing everything you own including your reputation should the worst (unmentionable) should happen!
I suggest that you find a kitchen to rent and purchase insurance accordingly. You'll have to find a way to build it into your price to the client: only a small fraction of it. Your insurance should not cost you much, depending of its duration of course.
I wish you luck, but in this business you only need a good head on your shoulders, skill and confidence.
I'd be happy to guide you through your process. I've been doing it for the last 20 or so years. I am now retired after selling out to my partner.
pm me if you wish.
