Didn't see page 2.
Anyway, Thanks for doing this - super cool to hear about you and dad working together. I used to dig holes for my father haha. Wasn't as fun as you're having but I learned a lot. Don't care what your product is but I'm interested in your process for finding a supplier. I know that you mentioned you deal with a US manufacturer. That's smart! Did you use any sites to help in finding them?
We did a lot of google searches, and then talked to about 30 manufacturers until we figured out exactly what we were looking for. The hardest part is finding what exactly you are looking for a manufacturer. For example most people need an OTC manufacturer and they don't even know it!
