We appreciate your considering us for your services, but have retired and are not doing any of the actual work. We are hoping to sell the business, at which point your request will go to the new owners. For now, we are not able to help with service requests.
For our established customers, we are willing to offer advice, recommendations, or brainstorming sessions. That can be done by e-mailing email@example.com; put "Customer Info" along with a topic in the subject line.
