Turn a small drill press into a Bore/ Hone. Bolt it to the top of your engine block & do your own machining .

For fucks sakes, send me $2500 and I'll ship you my old van norman 777s boring bar setup. Its complete with all the cutting bits, the tools, the various sets of catspaws, and the tray micrometer. It's in a nice roll around cabinet also.
I have all I need to do just one bad cylinder on the block I have that's already been bored .030" over. Evendently the prior engine builder didn't torque the heads enough and water got in this "remanufactured" long block , one cyl got toasted. So I ask you, do take it to the machine shop and get all done over again OR just fix that one cyl. to .040" over ? by slandering an old 4" piston with valve lapping compound to start with. Then use a magnetic drill with a heavy duty honeing head and adjustable expanding stone set. Then when it reaches the .040" over mark finish it up with the Lisle 15000 honeing tool ?
