Online Children's Boutique

I have given a lot of though to opening an online children's boutique.  Being a mother myself, I am well aware of the fact that in America, we spend more money on our children than anything else.  I would love to be able to open an online children's boutique.  The start-up cost with an online business is lower and because it is online, I could set my own hours rather than being consumed by a start-up within a building. I have found it to be extremely difficult to find boys clothes along with girls clothes. Another advantage to opening online would be to reach a larger demographic and not be confined to my general area. ( I love that online marketing makes it easier to reach a larger group of people. )
