Andy,
Feel for you on the death of your dad, tough one that to deal with.
Marketing wise I'd say that leaflets are only part of the answer. If you think of marketing as a wheel with spokes which are the different forms of advertising you do which go to the hub in the centre, which are sales. If you only have one spoke you aren't going to generate many sales. So add more spokes to the wheel. Website, leaflets, Thomson Local, Yellow Pages, door knocking, emails, Adwords, Facebook and the most important of all, repeats and recommendations etc etc.
