Foundation Assurance Letter

I need a letter for my seller confirming that my concrete slab foundation is sound. The letter should include the following details: - The foundation type is a concrete slab. - It was recently inspected by a professional. - The inspection was conducted by a licensed home inspector. An ideal candidate would be a professional writer or someone experienced in drafting real estate letters. I need this today if possible, the engineer I already hired isn't getting back to me now for 3 days and my buyer is about to pull out.
