How to approach a business owner about coming in with them in business..?

I have always been praised for my baking skills, I bake locally at a church and always asked to bake and sometimes sell my items. A local tea room just closed, but a news/coffee stand has bought it. I was thinking of contacting the new owner to see if I might go in with them to sell pastries and such at the store when they open. The business already has a business kitchen since it used to serve meals so they would not have to add to the location, so the only cost would be health inspections and cost of cooking and product. What would be the best way to approch this owner. I have looked into opening a bakery in town, with growth of the town and lack of supply of this item I was told it would do well, especially if a coffee shop atomosphere was put into place. So when this business was at the local chamber of commerce meeting (I was catering) I thought it would be more cost effective to join that compete. Any professional advice would be appreciated

Write up a business proposal and show the owner of the coffee house the benefits of the merger. Do your research and take into consideration what it's going to cost YOU to take on the 1/2 of the business. Keeping up the kitchen to code, buying fresh baking ingredients on a mass (hopefully) scale. You might want to think smaller and just ask the owner if they're buy, whatever amount you can comfortably affordably make from home, X amount of baked goods from you on a daily basis. That's a win/win. Lower cost for you and them, and hey, people are going to drink more coffee if they're eating something!!!!!!!!!
