Not sure if they are available in your country but maybe checkout Bitwage. They allow you to receive your pay check in bitcoin. Pretty sure a few stackers here use it. I know I have heard @DarthCoin mention it.

Trading services for bitcoin is another way. Do direct work for bitcoiners or sell something online for bitcoin.

If you wanna trade fiat for bitcoin checkout Robosats.

You could also ask for ideas by posting a discussion on SN about this topic. I'd search for it first though. There's a lot of data on the site already.
