Good afternoon, MGK design. Hi. I'm looking to have plans drawn up for an addition in my house. Okay, let me have one of our architects return your call. May I have your name, please? My name is ####. ####. And your last name? My last name is #####. Would you spell that for me, please? # # # # # #. Okay, and your telephone number? Area code? ###-###-#### that's ###-###-#### yes, ma'am. Is there a good time to reach you? That's my cell, so he could catch me anytime on that. Okay, great. I'll have him return your call as soon as possible. Great. Thank you very much. You're welcome. Bye.
