I'm not sure what happened here. Apparently this would-be seller changed his mind about selling to you but did pay you back, since all you state you want is interest for 3 months on $10,000. That's very little given the relatively small amount at issue, how low interest rates are now, and the short time frame, probably not even worth a Small Claims case.
If there's more to your story --and it seems like there was "conversion" of your property, but maybe you've gotten it back-- see a business litigator.
Avvo doesn't pay us for these responses, and I'm not your lawyer just because I answer this question or respond to any follow-up comments. If you want to hire me, please contact me. Otherwise, please don't expect a further response. We need an actual written agreement to form an attorney-client relationship. I'm only licensed in CA and you shouldn't rely on this answer, since each state has different laws, each situation is fact specific, and it's impossible to evaluate a legal problem without a comprehensive consultation and review of all the facts and documents at issue.
It seems you did not have a written contract for the sale of the business, is that correct? Unfortunately, if the terms aren't clear enough, you may have a tough time suing for your damages based upon breach of contract.
Even if you win, you will not be awarded prejudgment interest unless you can show that your damages are capable of being made certain by calculation. California Civil Code § 3287 (a) provides that “Every person who is entitled to recover damages certain, or capable of being made certain by calculation, and the right to recover which is vested in him upon a particular day, is entitled also to recover interest thereon from that day, except during such time as the debtor is prevented by law, or by the act of the creditor from paying the debt.”

Your fact summary is very complicated and it sounds like you have a huge mess. The other two lawyers have given you excellent advice. It is probably worth meeting with an attorney to see what your rights are, if any. As Attorney Koslyn pointed out, if all you are looking at is interest for a period of 3 months, then it may not be worth it for you to pursue.
Conversion, or tortious interference with a contract, or some other torts involving the wrongful taking of your property might be worth considering when you meet with the attorney. In Michigan, some of these violations can lead to punitive damages.
