One little minor, minor adjustment - when people sign up for your mailing list, in the email From line, your name is listed as "DAvid". So, so minor, but caught my eye. Thought you might want to update the capitalization error.

I don't have a list that meets your niche market, but I know someone who has (Mike) and have sent the info along to him. Hopefully you two can work together

All the best!
