How do you make first contact? What information do you present on first contact? What basic steps do you view as key check-points to move through in the process? Any relevant advice appreciated!

I’ve been operating a direct to consumer surfboard brand/factory for over ten years and we’re now looking to expand by selling to other retailers up and down the coast. I know our product is unique and valuable, but I have no B2B sales experience and want to make sure we don’t squander first contact with a bad pitch process.
