As previous posts it's not a difficult job and any decent radiator shop can pressure test and clean the cores. But if you aren't comfortable with a job like that you are better off paying someone else that has experience.

They have a great reputation. not sure how far they venture out of grand haven storage but worth a call to at least get a competitive estimate. Drummond marine in Holland has a couple of great diesel techs that are very well respected. If you call them ask for Moe or Ed.
