Get a private swim instructor to come to your pool to teach you how to swim 1-on-1, at your convenience. It should cost you about $40-$80/session, where each session should last 30-60 minutes. If you do 3x/week, you should be able to swim freestyle within a month. ~$750 investment to learn basic swimming is absolutely worth the investment, especially if you own a pool.
After that, feel free to stop or learn more for other strokes.
