As Mr J_B says, keep doing the distribution etc yourself.
Your website is good; and you should link up to as many other harmonica sites like this one you can find.
You should also think about going to a SPAH and/or other harmonica conventions you can attend.
Once you make your first $Million, then you can hire others to work/sell for you.
Put me down for that!
