good engine machine shops in pdx area

im looking for a quality machine shop to do the work on my stroker.
ive never built a motor before so i dont have any experience with machine shops, or what to look for and what questions to ask.
im also not all that rich, so im not sure if a full race shop will fint in the budget.

my dad has his chryco big block at paola's im clackamas, but he isnt concerned about price or timeframe on that motor.(they've had it for 6 months and havent started it yet.)

any suggestions?

EDIT:

actually its paolo's engines in oregon city
