I've not used NaOH for board etching, but I believe the "perchlorure de
fer" to which you refer would be "ferric chloride".  While I've used FeCl3
to make boards before, I think sodium persulfate (Na2S2O8 I believe) is
better.  Another poster mentioned a method using H2O2 and HCl: I think it
involved immersing the board in H2O2 and adding a few drops of HCl; once
mixed the reagents had no useful shelf-life, and good ventilation was
necessary during the process, but supposedly this method worked quite
well.  I would strongly suggest discussing it with someone who was
knowlegeable about chemestry before trying it, however, and don't try it
without wearing goggles, gloves, and a splash-shield, or without ensuring
that you have adequate ventilation.

As for UV lamps, I personally have found that "Press N Peel Blue" works
almost as well (it's a toner transfer system) when used with proper care.
The trick is to--after ironing the transfer onto the board--apply
strapping tape to the board and peel it off.  The resist will stick to the
tape in the areas where it "shouldn't" have stuck to the board.  If you
don't perform this step you're likely to have bridges all over the place,
but with this step you should be fine.
