Doug, I am very impressed with your achievements, but see your website has not been made as yet? I have a project YoungVoice that gives a free website with every website I make, funded by a paying customer and want to offer to sort your site out for you (If it is indeed the one I have seen that appears to be a holding page http://www.mypifi.net/
I love supporting entrepreneurial people and feel the website needs sorting to make it more of a success for you and your sales ongoing. I will not charge you for this as I want to see this work for you (truly philanthropic motives).
Please do feel free to email me email@example.com
and well done with achieving your goal and your second product.
Check out my RaspberryPi connected to a container delivery truck. Search YouTube for iDataTruck - more being added too.
