Finding gigs is always a challenge. At least ones that pay a decent wage.
I'm happy to have what I have.

As for repertoire, I play Road Song by Wes and a couple of Crusaders tunes. George Benson, Dolly, Don Gibson, Willie, etc. I currently do Wichita Lineman also by Jim Webb. I'm 65 years old.

I chart most of the changes from Real Books, IrealPro, artist Music books, or charts I find online. Some I do the hard way by Transcribing.
YouTube is a great way to figure out difficult heads. There's a lot of guitar players on YouTube much better than me. Some are amazing.

I've not found much long term success using other peoples work (mp3's) for performance. Often the levels or EQ is just unacceptable. Sometimes an instrument is too loud or two soft. The cymbals are often too loud. Its difficult to mix in other parts. Sometimes no amount of work in the DAW makes them good enough. You can hear the difference between tracks. For me It has to sound like one band, not a bunch of different bands. Consistent volume and EQ (bass and highs) in your tracks will separate your stuff from the others. It will get you gigs. People often comment on the quality of my stuff. It sounds good. It takes work.

You'll find your own road. Enjoy the journey.
