To each their own - but I would not captain a USTA team if you paid me. I see what they go through! It's a stressful part-time job with no pay.
Is there anything else in your area, like Ultimate tennis, Tencap tennis, K-Swiss, a USTA or non-USTA singles flex league? Even those, to me, would not be enough on their own and would only augment my main play, which is recreational.
What I did when I took up tennis (both times, 20 years apart) was join local tennis clubs and join their singles leagues and ladders, and this got me started. I also had the manager fix me up with some people. (It's to their benefit to get you in there playing.) It took a few months, but eventually I found some people who were a good fit who wanted to play weekly, or even more often.
Recreational play with friends, to me, is where it's at. I tried USTA but found it not great for singles players. I think it works better for doubles players or young people who are really good and looking for competitive play to get better.
