D1 head gasket - shop/mechanic recommendation?

I need to do a head gasket on our D1. Indicators are gradual loss of coolant over time (months), clear coolant but film on surface in overflow, clear oil with no signs of coolant.

Naturally, this coincides with my peak work-travel period, so I'm considering farming the job out. Only problem is, who?! Anyone have a trusted mechanic or club member they recommend? Preferably close to Western NJ area (Frenchtown NJ), and drop-off ASAP...

Post here or contact me directly.

Thanks in advance,

Tom P.
