I think that it would depend on where you live, to how you advertise.
A small town with no-one in it, the shopfront sign may come across as
nice, cosy, honest, affordable, local, etc.
A big city with the same sign may come across as
dodgy, sleazy, broke, etc.
There was a thread a while back that discussed a few methods and ideas
on advertising:

Otherwise you could do a search for 'advertising' on this site, I'm sure that
you'll find something, or just wait for someone else to give better advice than me, hehe.
