I would recommend that you sell the powerbase within the Network, it has little value outside CD.
The powerbase is in fact a modified Hydramaster RX20 , sold at a vastly inflated price. I would be very surprised if CD head office did not make your life difficult if you try and go it alone.
Have you got anyone who can front the new business for you , and mail out to your existing customers?
Good luck in your new venture, I left CD 8 years ago, and have enjoyed my work far more , and have benefitted financially, far in excess of my fellow franchisees in general.
