Hallo Sasa. I use my blog, my personal web side, my mails to advertise my SFI business because I don´t know where and who will read them. I write a newsleter ones a week in my web/blog and send it every where I am linked like Twitter, Facebook, Xing, Myspace etc. It is not a guarantie that it works but it is advisable to use every posibilty to advertise your business. The best way is always direct contacts ofcourse but we have first to find them.
