Randy if your not able to find someone nearby you will need to haul the car or have it hauled a farther distance to someone able to do the work. If that is not an option then it will be necessary to pull the engine out of the car and put it on a pallet and ship it to someone else.
Removing and installing an engine is much simpler than opening one up yourself and doing the work especially if your not familiar with the internals of an engine.
Myself I don't relish the thought of trying to adjust the bearing clearances with the engine in the car. I've always pulled the engine and done it on a stand. Once on the stand I disassemble the engine to the point that the crank shaft can be lifted out to assess the condition of the babbit in the block itself. Doesn't take a whole lot more work and then you will know the condition of the engine as a whole.

Another option is to try to ignore it and run it until...
