EMAIL (Best Way)

The most efficient way to contact us is by email.

  • Emails are generally Not monitored evenings or Sundays.

  • Please allow 24 hours for a response, but in general it will be much sooner.

  • If you do not get a response in 48 hours, either A. We did not received your email, or B. We responded and it is sitting in your junkmail folder.

  • Include a phone number on emails so we can contact you if your email is bouncing back.

  • DO NOT SEND EMAILS WITH OVER 10MB OF PHOTOS.  Please resize any images to a reasonable size.  Emails larger than 10MB will not go through and, depending on your provider, you may not get a bounce back.
