For the foreseeable future, I will no longer offer audio guest books for sale. I hope to continue the business later this year from my new home in Europe, but that remains to be seen.
It's been an honor to build and convert these phones for you and for the special events and memories they helped capture. I encourage you to seek out personal builders of audio guestbooks for your business or event, and shy away from mass-produced builds. You'll spend more, but the quality and service you'll receive is worth it, and the importance of these events deserves that higher quality.
I wish you all the best going forward. Feel free to still message me with any questions you have, advice needed, or anything else.
