Are there flute makers like casey burns who are based in ireland that deal with the same amount of detail for people with small hands. also what would be the main differences between his flutes and the cotter keyless i am currently using aside from the smaller size holes in the flute.
Seery does a small hand flute, too. I’ve not seen one, so his definition of small might be different than Casey’s…

One difference is obvious even to a dabbler like myself - the Burns flutes have his “ergonomic” layout - the finger holes are laid out in two arcs rather than in a straight line (this also means you’d need to special-order a lefty model from him if you play lefthanded).
I’m still struggling with a Dixon 2-piece cylindrical flute, but I’ve had a chance to try a couple of the Burns Folk Flutes and they are much easier to finger than my Dixon, or the Hamilton I got a chance to try the same day. I’ve got medium-sized male hands and had no trouble with the standard ergonomic layout (or, to be fair, any conical flute I’ve tried with straight-line holes - but the Burns was easier). He also makes a small-hands ergonomic layout - I can’t imagine he couldn’t make a flute to suit you.
I believe the Seery has a straight-line hole layout, but have never seen one in person. But I’ve been impressed enough by reports that I’m thinking seriously about the Seery as a possible next flute (or the Burns, or an M & E, or the Ward flutes).
I don’t know which would be the most affordable for you, though. Here in the US, the Burns is probably the best bargain at $250 new.
