Recommended Mechanic To Smoke Test For Vacuum Leak

[EViS]

My yank Ford F150 has developed a rough idle, I suspect it's a vacuum leak somewhere which I have been unable to trace. Could someone recommend a good mechanic who can smoke test the lines/manifold for me and get the V8 running silky smooth again?

Thanks, any other recommendations chaps. Doesn't have to be an 'american specialist'.
