Are they any local networking groups you can join? Think about who your clients are and where they are. Also Twitter hours can be good for finding other local businesses, I'm sure there's a Notting hill one or similar. That way you can get to know people.
Look out for any local business fairs or similar. And maybe take a look on LinkedIn and see if you can use that to your advantage. Facebook can be good for targeted marketing but you can do it for free if you join some local FB groups for your area and her to know people and other services when needed, not just sell sell sell.
Best of luck.
