Hi,
Your project sounds very interesting and I would really love to work on your project. I've done similar projects before and can provide samples of my work. However, there's quite a lot of clicking involved in the process (especially since you don't know in advance whether the post will go through or not :S Also, changing IP addresses and creating new account for each post is not that difficult, as much as it's a bit time-consuming). Nevertheless, I like these types of projects and would enjoy participating, only at a bit different rate - $3 per post/link sounds fair to me, and if it sounds fair and affordable to you - I'm all ready and willing to start :)
As for my other experience here, I've been working mainly as content, article and blog writer; but, I've also done some other things, like audio transcribing, data entry, even some small programming :)
Should you have any questions about me or my work, just shoot and I'll be happoy to answer. In the meantime, check my reviews and kindly consider my bid.
Kindest regards.
Isidora
