Also, set up a website and run from that, it's not that expensive.
Its not so easy to set up a website with no exposure though...
Here in the states we really dont have any free directories so every place we advertise there's money involved. There's also been several sites who have started charging when at one point they didnt e.g.
craigslist.org Its unfortunent because some days you may be low on funds and have to decipher between paying my advertising or paying for other things. Of course if I dont advertise I dont get exposure or make money so there it goes. Also, when listing on mulitple directories the bill comes in...sometimes all at once and can add up.
Its fine when things are rolling, but when it isnt you can end up spending more on advertising than you earn from it. Ridiculous.
