Hey! I am fairly new too, and took over a shop in November... although it's slightly different to what you are doing, I would totally recommend you get back in touch with Biz Gateway. The guy we saw when we were about to set up was soooo helpful, even gave us his home number in case of emergencies! He went though everything from the partnership agreement, to borrowing money. Don;t know if you knew, but they can also help you source grants... we tried for this, but we were too old!!!!

Good luck!!!
