granted. so if the Op makes phone calls on day 1 (a Friday), how many return calls will he receive on day 2, a Monday? Doing anything on a Friday, aka take out the trash day, is just a game move to make things harder.
Lawyers understand that it takes time to get counsel for yourself. My experience is that if OP says, "I am in possession of your letter. I am in the process of retaining counsel. Please provide reasonable time for me to hire one and provide a full response," then that should be adequate. It's a standard response to such letters.
