Look into filing a breach of contract suit yourself. in my opinion, threatening lawsuits is silly and the only stands to make you look bad but filing one shows that you're serious and puts you at the top of the payables list.

In some venues it's very easy to file cases like this.

This is only possible if the contract is with him individually, instead of an entity he created. In most places, a business entity cannot represent itself in court. It needs to hire a lawyer.
