My business has practically doubled since starting a facebook page and regularly posting photos, people don't realise how many different things we can do these days so this lets them know. Share your best posts on your personal page too.
Another huge boost was when I started sending a monthly special to everybody whose email address I have. Advertise one different thing per month (I've got a list of 24 specials which nicely spaces them two years apart), again this is more about showing what you can do but is aimed at businesses rather than friends. Nobody ever takes advantage of the specials but the email reminds a lot of customers that they hadn't got back to you about a job, or reminds them of a job they'd been intending to contact you about.
