Custom orders?

I suspect there is money to be made in building things to order.

This was made as a gift, so not exactly a custom order.

The recipient was pleased with the result even more than I anticipated, but I have worked in enough customer service situations to know that custom orders mean deadlines and a very high risk of hearing the words, "That is not what I wanted."

As I continue to debate with myself about this, I suspect the answer will only be determined when the specific situation presents itself.
