Yes this one is a good method to improve our rankings.I do agree with you guys..
We are looking for some one experienced with forum posting and classified submissions as well - to work for us on a regular basis.
* Forum posts - One or two posts are enough per forum (better a new thread with a link to the website - Not signature link - So you can post from your own accounts - No need of new registrations and all).
* Classified posts the same like forum posts - One post in as many as classified websites (in sites with links only)
Let me know how many forum posts and the number of classified posts you can offer and the exact price per post.
If the first attempt works well - this will be a permanent work.
