internally balanced 360 crank (BIG PROBLEM) need input

thanks to everyone for all the input again i pulled the motor and gt it on an engine stand yesterday it was a painful 3 hrs cause i just finished putting it all in and it sucked to have to take it all out but either way the deed is done i told my engine builder that he can deal with the crank supplier because he bought it and i had no control over that and that im not gonna be a middle man i told him that if the guy wants to cover all the cost of parts including fluids and gaskets i would consider him doing any machine work at his shop i want a properly balanced crank ( that i now know what looks like and how it should be done) and if he supplies everything needed i will eat the cost of the R&R but i want my engine builder to assemble the motor so we can inspect all the machine work and i can see it being put together basically he would have to replace all that anyway he will only be paying for the cost of assemble which is dick like 400$ i think that is a fair deal and something i would be able to be happy with is that too much to ask? i dunno i will find out in the next day or so but i took lots of photos last night that i will post right now also he can cover the cost of a bag of kitty litter to clean the liters of fluid i spilt in my tiny garage lol
