UK government is investing a lot of money in satellite, Harwell is going to get busy and ESA is going to move in (http://www.esa.int/About_Us/Welcome_to_ESA/ECSAT). Eventually there will be accessible testing and launching facility too for micro satellites and the like! Nothing is missing in your plans now, only action.
If you are not prepared to launch satellites, are you prepare to invent using the data from it? UK European Satellite Navigation Competition (http://ukesnc.com/) is open until 30 June. It's a competition where you are encouraged to submit proposal for the application that uses satellite data. Check out the previous winner section.
