Make sure to get the 'latest' version, it really makes
a difference compared to older versions.

I can recommend OSHpark as pooling service if you do not
need the boards urgently or have specific requirements
regarding layers or vias or whatnot.

I've done quite a number of PCBs via OSHpark, from small
breakout boards up to quite complicated FPG solutions
used in a 4k cinema camera.
The essential points with OSHpark are (in a nutshell):
- drill sizes are "optimized" i.e. they have certain
tolerances and you will not always get what you expect..
- you have to use one of the three different stackups
if you like them or not :)
- there is no electrical test for the PCBs
- there is no impedance control done by OSHpark
- you always get multiples of three boards
- the boards are purple with white silkscreen and
ENIG finish on the pads.
Hope that helps,
PS: if you have more detailed questions, do not hesitate
to ask me ...
