Limited-quantity PCBs; where do I get them?

I have a very simple design for my microcontroller, using an accelerometer and distance sensor. I have a couple of Protoboards right now, but for each design I need 14 connections made and naturally I spend a considerable time on soldering parts together - not to mention the limited durability and reliability of wires in the first place compared to a printed PCB.

I'd like a single-layered printed PCB that can make these connections for me, and has through-holes for mounting my microcontroller and sensors onto. Basically a regular Protoboard but with connections pre-made on it so it doesn't require any wiring. I have a limited budget and don't want to go ahead and order tons of them as my little project may very well not work out as expected - so I'd like to limit it to 20-50 boards only.

Does anyone have any tips or suggestions? Especially since this is not an industrial-grade and highly-complex PCB I'm requesting, but more like a hobbyist thing.

The Products and Services section of the forum has posts from manufacturers making small quantities. Usually, they'll make 2 or 4 (depending on size) to allow you to test the final product before buying more. The first set is usually very low price.

Alright, I'll head over there, thanks!

OSHPark for domestic (US) production. DirtyPCBs, PCBWay, or Seeed for much cheaper production in china.

if you can make the drawings with some sort of pcb program, you can have a lot of options.
I really like itead. https://www.itead.cc/open-pcb/pcb-prototyping.html

depending on size, you can get 10 boards for $10.
if your boards are smaller, you can get two boards on the 5cmx5cm form, if they are smaller still, you can get more per 5x5 footprint.
