I live in Ireland and work with my Father doing a plethora of things.

The way it works in my little town is almost mostly be word of mouth with little real advertising of your trade.
I paint interior and exterior houses, repair nail guns, power wash, refurbish furniture and a lot of other miscellaneous things that we realistically can do.
I've been doing this since 17 and I'm now 23.

There is no official business to point to or anything like that on a resume and I'm unsure of what to even list there.
I could absolutely use previous clients as references but I'm not sure how far that will take me with employers and It'd be a headache to call people back up again (but necessary if it helps) and scratch our brains on previous work.

I'd appreciate any suggestions or just forward answers as to whether I am able to list all of the things I did over the years on a resume to show there is no gap in "employment" and I've been working all these years.
I don't have much intention to pursue this type of work much longer and I intend to seek further education and potentially seek out web development, so this will indeed be my first time ever figuring out a resume.
Side note, is this type of work considered work on paper? It's all family business townie work after all and as I've stated above, not officially licensed in anyway outside of a business card.

Thank you for any replies in advance!
