Hi Julie
Like your site, its nice and simple and easy to navigate.
Might be worth you trying google adwords - I got £30 voucher to start me off free of charge and I now spend £30 per month. I'm still refining keywords but google will do lots of free analysis and reports for you so you can keep tweaking til you get it right. I'm meeting up with someone next week who's going to give me some free tips so when I'm more confident in what works I'll post on here so everyone can benefit
Also, I kept putting search terms into google and every web directory that came up on the first page I booked a free listing.
For me marketing is about finding what works, testing it in small amounts, then when you are sure its working, ramp it up to whatever your desired outcome is - i.e. if you want 10 times more customers, spend 10 times more on the right marketing!
Hope that helps
Diane
