It is official, rods are toast. Now rebuilders

Taking something to an "engine guy" "carb guy" "rebuilder" etc is just asking to be overcharged for something like that because you don't know how to do it yourself.

Pull the engine, put it on a stand and tear into it. Your absolute priorities are bagging and labeling bolts so that you don't lose them or mix them up. The "everything in a can" method won't work. Next is to mark the rods so that you know where they were in the engine and what direction, and also match mark the rod caps to the rods and main caps to the block so that again you know exactly where everything was.

Once you get everything apart you can take the parts to a good machine shop to have the block cleaned and honed/bored, the crank inspected and turned and the rod with the bad bearing rebuilt if necessary.

After, you can either bring everything back and assemble it yourself or have the machine shop assemble the longblock for you.

Just remember that it'll take over your life for a month or so and it's vital that you ahve a good area to work in and that you are capable of devoting the necessary attention to this kind of thing as well as actually being motivated to do it.

Otherwise, haul it to the rebuilder, let him handle it then write a check at the end.
