This may or may not help you, but maybe someone else reading this, I've officiated youth and adult sports on the side for close to 20 years and its great side money, you can pretty much make your own schedule, and be exercising a bit.
You need a bit of a tough skin b/c of the current way youth sports is and officials have an easy target on their back, but if you are good at it and confident, it can minimize the issues.
I officiate ice hockey and you really have to have some skills like skating and such, but other sports have a little less of a barrier to entry. If interested, reach out to your local school or youth organization in the sport you like and ask them who handles the officiating.
