I’m a big music lover - and I’d love to be able to play guitar better than I can at the moment, and maybe sing a little, but I just can’t afford it and, to be honest, I don’t know when I’d have the time to deal with someone else’s schedual considering I’m up for three days at a time then out like a light for 12 hours.

Something that sound promising is Amadeus Home Music School. I’ve never in my life heard of music home school, but apparently it was founded by actual music teachers and is a lot less expensive than average music lessons. Might be worth a try!
