Hey Gotti:
Good luck w/that.
A good first step would be to do your research--begin to put together a business plan. You'll need to put your vision down on paper to make sure you've thought every aspect through. Here's a good site:

With the research you will do on your own, you can tweak it for a UK context if need be.
Peace
