Good diesel shop in Orlando?

[Classicfordguy]

Can anybody recomend a good diesel shop in or near Orlando Fl? I need to track down my mystery knock and I think it's probably injectors so I would like to get them tested. Never taken the truck to any shop before so I don't know any good ones.

Also, how much should it cost to have 8 injectors tested if I take them out and take them in?

Thanks,
