PCB Manufacturer

[Luca82]

Hello,
I'm looking for a good PCB manufacturer for a 6 or 8 layers PCB with thin prepreg in order to have 40 ohms single-ended tracks on BOTTOM using 100um wide tracks (approximately).
Do you have any suggestions ? In Europe or USA or else ? I know Robert talks about SQP International in one of his blogs, I got in touch with them but they are too busy....
Please, anyone have suggestions ?
Thanks !
