You can do a basic website for free - Wordpress.com for example - and you can register a suitable .co.uk domain very cheaply, 2 years for the price of a reasonable bottle of wine. For what it will cost you I'd say this is well worth doing, and all sorts of surprising people use the Internet. An old friend of my fathers (the friend is in his late 80s) for example - though since he lives in a flat with a small balcony nowhere near Manchester he's not a potential client.
BTW I think there are still some issues with the leaflet. "From only £10! Per Visit" should be "From only £10 per visit!", and I'd put it all in black. Changing colours chops the sentance in two. "From only £49.99" should all be in the same size font, and I'd put it all in the same colour. Surely 'from only' is as important as the price?
