Haven't advertised in 8 years and don't have a website. A bit different for me though as on an island with limited workforce where word of mouth is all that counts.
Nothing replaces recommendations by clients, past or present, it will always be the best form of advertising.
It's only restricted by the number of people your clients come into contact with and to some extent their standing within your local community.
Hence the term, 'not what u know, it's who u know'.
You are in a unique position tho Harry because, as u say, there's a limited workforce on the island.
So they're lumbered with who they've got on the island! Hahaha
😛😛😛
(Obviously only to some extent, cos labour can be brought in)
Trouble is in larger populated areas, if u haven't been lucky enough over the years to meet those 'useful contacts' you probably will still have to advertise.
Right place, right time syndrome.
I don't have a website perse, but I have elaborate photo album that only potential clients can access, but that's only if I supply a link.
.....and the last time I actually advertised was 1987!
