Commercial Damage Demand Letter Creation

I need a concise, professionally-worded demand letter that holds a business accountable for recent damage to my commercial property. The letter should clearly outline the facts of the incident, reference any pertinent statutes or case law that strengthen my position, calculate the repair costs I will be pursuing, and set a firm deadline for payment or satisfactory resolution before I proceed with litigation.

Please craft the document so I can simply add my letterhead, sign, and send. A polished Microsoft Word file, plus a PDF version ready for emailing, will be the expected deliverables.
