Hello! I'm under contract to acquire a business that has a large amount of seller financing. There were a lot of cash transactions, so we have included a right to set-off the note inside the APA, and are looking for a way to arbitrate that in the event it is needed. Looking to protect myself as the buyer if it turns out labor or inventory were being bought under the table, and the seller (understandably) is not willing to leave the full discretion on setting the note off to me as the buyer.

Can anyone recommend a company that offers dispute arbitration services that we can have on deck in case it is needed? If anyone has used services like this before, around what price points have you seen? This is a smaller transaction (under 500k).
