Looking for a Mobile Diesel Mechanic for a pre-purchase inspection

I'm looking for a diesel mechanic in the Astoria area, preferably mobile but could be a shop diesel mechanic that is willing to a make a house call. I'm looking at purchasing a Ford 7.3 PS vehicle and need some more seasoned eyes

I've looked through all that Google brings up and will be calling around on Monday to find someone. Any recommendations are more than welcome. TIA!
