Custom FSR Matrix - Looking for manufacturers

[PeterFW]

Hello! 
Has anyone experience with ordering a custom FSR Matrix? 
I already ordered a sample at Sensitronix and the only other manufacturer i found was Kitronyx but they are out of my price range. 

Looking for something along the lines of 30x10cm with around 4 sensors per mm². 
So... round about 12 by 4 inches at maybe 25DPI 

I do not need a custom one, but i have not found something in that size.

Greetings,
Peter
