What's wrong with doing it yourself?
We have some very good "How-To's" avail. that will guide you right along.
Many folks here have changed out there cams, heads, headers, oil pumps, etc by themselves with very good results.

Re: 98Z28 Oil psi low..... the job isn't too hard, just gotta watch the o-ring on the pickup tube. The part you can get from Katech or thunder racing, they both sell the same pump, Katech ports them, and they flow very nice.
as for a shop, it's in FL so I have no clue.

Re: 98Z28 Oil psi low..... just pick up a ported ls6 oil pump and new o-ring and swap it out yourself.
cam/spring swap but it also shows you how to swap the oil pump.
