First of all, my condolences to you and your family regarding the loss of your Uncle. My suggestions to you are to start reading voraciously about all types of different recording gear, ESPECIALLY pro stuff. There are various Pro magazines you can try (Mix, Audio Media, Electronic Musician, etc.), as well as magazines covering consumer gear as well. When I studied Audio Engineering some years ago, one of the first magazines I started reading was Mix. I also grew up reading various consumer magazines like Stereo Review, Audio, High Fidelity, Stereophile, etc. (some of which aren't published anymore).There are many articles and some magazines that you can find online as well. Audio Media is a pretty good one (link below).
I started in the industry after attending Center for the Media Arts in New York City for a year, and getting internships at Platinum Island Recording Studios, Unique Recording, and Battery Recording Studios. Although I'm no longer in the recording industry, that's how I got started. My advice is to start reading, get information on different studios, local radio stations and TV studios and schools in your area, talk to the people there and ask their advice on how to break into the business, and also continue to listen to as much consumer gear as you can and continue learning how to listen, what to listen for, and all the different audio terms that go with it.
And don't forget: you are NEVER too old to learn and follow your dreams. Just make your mind up, and do it. And don't be afraid to try, and keep on trying! Good Luck!
