How to market hand painted mailboxes??

I just started my site this summer and I've only had two buys, I don't
know if it's against google's terms of use to post it- I couldn't find
it from what I read but I'm really looking for advice on how to make
the site better ot how to get people to visit it- I'm spending too
much money on google's "as words" but it's the only thing I can think
of -any help would be appreciated.
thanks!
