you could try putting flyers up
in your local chippy, shop, doctors, community centre,
ladies loo's in pubs, shopping centres , speak to your local taxi firm and ask if they would put some business cards in the cab's for you (another geek ladybgemini has done this , and seems a good way to advertise)
Try to think of anywhere in your area you ever have to sit and wait bored, !
because when you are waiting for something and you are bored , your eyes will search for anything to read to make you look busy lol ,
so make sure your flyers stand out, go on a little walk and look around to see what flyers grab your attention and which ones you wouldnt bother reading, then look at why !
