Set up and run a facebook group with small store

We have a B2B & B2C vintage fashion range. We would like to promote the stock via facebook in order to run ad hoc flash sales etc. We will also develop a pop up retail concept with facebook seen as the best local medium for attracting existing & new users to those stores. The facebook page and ecommerce website exists the facebook store does not.

Initially we're looking for a professional facebook operator. Thereafter experience of selling on facebook will be helpful.
