How much space do you have? You should be able to upload the file via FTP and then give your subscribers/visitors a direct link to that file so that they can download it. This generally works with any host (provided you have enough space & bandwidth with your account).
For example, I uploaded this PDF file to my account, in a folder named "free", and so this is the download URL:
http://www.selfstartersweeklytips.com/f ... report.pdf
Does that help? Or are you looking for something different?
As for classifieds... I've never had very much luck with them, but I would be interested to read the details they gave you on that. There is ONE site that I'll post ads, but it's a very small local classifieds site that is promoted heavily offline via the radio around here...
Anyone else?
