Express gratitude for an offer, but state that you're busy with your hobbies. Then, mention your question regarding FAA certification in relation to drones.
Silver City is 4 hrs south, but I appreciate the offer -- and I have a hobby, amateur rocketry (HPR level 1 so far).  But thank you for the offer.  My other hobby, Burning Man, which has me VERY busy at the moment, gives me familiarity with drone operators doing stupid stuff, so my question about FAA certification.
