I'm just got back home.
I have the new boards and almost all the components to get them built

That is good news! Is this the second batch of boards that have the fix for the spacing of the audio connectors? How many boards are in this second batch, another 50, or was it 100? I hope I am on the list to get one of them?
I hope your efforts to turn this into a commercial product are going well and you will soon have the opportunity to sell thousands of them, but finding retailers that will commit to purchasing large numbers of them is probably a hard thing to do for any small startup company. Plus the cost of packaging, marketing and peripherals, like the case, PSU, etc. all add up and may make the product too expensive for large retail distribution.
Still, I wish you luck MikeJ and I still think that the Replay board is a large step beyond the original MiniMig, so you might find that someone like ACube or AmigaKit is interested in selling them.
Edit: What is the amount of time it takes to complete the production of this second batch of boards? Is it a certain number per day, or does the production facility assembly all 50 or 100 boards in a few hours, since they are mechanically assembled, not hand assembled?
