I think you may have to review your design because it's too small for PCB manufacturers to prototype.
Würth Elektronik can be a good recommend for you to achieve such PCB prototyping,but of course you have to pay more.
I think 2mil width/clearance is quite difficult for normal PCB manufacturers,maybe you can quote from some Japanese suppliers.But the price must be very high.
