Thanks Hobow but as I touched on earlier - this being Ireland, there's not much call for the likes of "pickling supply stores".
I did, however, look on the Irish golden pages for taxidermists and have found a few that are withing travelling distance for me so I'll make calls over the coming days and see what I can find out.
Also... in slightly gooder news... I've found a company in Scotland that sells tanning & taxidermy supplies and they DO ship to Ireland!!! *pause for cheers*
So at the very least, I'll be able to buy in some chemicals and do some "proper" experimenting myself. *pause for more cheers*
Thanks for all the offers for help, guys - I'm sure I'll be PMing at some stage
