First, if price isn't a factor, there's Newport Components NMA0512S / NMA0512D.
They can deliver 1 W, and the price seems to be about 80 FIM in single qty.
(1 USD = 5.56 FIM) It is a module (about 1 * 1.5 cm) which already contains
everything needed for the DC-DC conversion.

Then there's MAX864, which tops at 20 mA and needs two capacitors, and isn't
exactly the chip you need - it generates double the input voltage on both 
the positive side and negative side so it's only +-10 V...
