The FA has opened a fund for setting up football teams. This is open to Deaf Specific as well as Deaf Inclusive Football teams not just mainstream only.
If you are looking to start a football team see http://www.footballfoundation.org.uk/funding-schemes/grow-the-game/
You can get support from your local County FA to complete the application.
A number of Counties through the Disability Football Development Fund have employed development officers to help develop football, most will support deaf football.
