AC/DC power supply 15W: flyback transformer design manufacturer

[logicnibble]

Hello!

I am designing an AC/DC power supply using a flyback topology for up to 15W.
Now I need to design the flyback transformer. I only know the transformer currents (peak, average, primary, secondary) and needed inductance.

Do you know any good transformer manufacturer that can design this type of transformer based on the specifications I have, supplying some samples?
Preferably in Europe.

Thank you!

Are there any flyback transformer designers out there that can help me?
