Eastern Members - In Need of a Machin Shop SC/NC/GA

I recently begun to put together my 383 build for my C5. Upong installing the timing chain Gear I some how got the crank bolt stuck.

I am having a hard time find a Machine Shop that can remove the bolt and retap the crank if the bolt breaks or the threads are cross threaded.

Hoping some of yall will know of a good place that doesn't take forever and decent price of labor.
Thanks
