I run a site called [url removed, login to view]
My site has 7,429 members and is generating over 15,000 views a month.
I am able to offer advertising space over the website. This will be at $40 a month, $110 for 3 months, or $400 for the year.
I am also selling about 100 signature spaces on this site from 100 members (obviously some are worth more than others).
I can make more posts happen from each user, depending on how many user signatures you would like to buy.
My prices: 10 posts a week from a user- $2 a month of signature space
20 posts a week from a user- $3.50 a month of signature space
50 posts a week from a user- $6 a month of signature space
You can also advertise through the avatars which is an extra $2 a month per user.
You can ask for up to 100 users altogether (as this is the maximum I can get to post).
All of these forms of advertising will greatly increase your traffic.
If you want any more information please don't hesitate to ask.
