My landlord threw my belongings out after I was evicted. What are my options?

I was evicted by my building's management and within 7 days after the eviction, my personal and business belongings were removed and trashed. Amongst the trashed items were personal items including my clothing, my children's clothing, my new furniture and other minor items. The business items that were trashed were equipment, uniforms and two file cabinets full of documents containing the personal information of my clients (social security numbers, birth dates, addresses, banking information and more). I was advised to seek out a lawyer to handle the lawsuit.
