Hi,
I am Sasa Sekaric from Serbia.
I am ruby and ruby on rails developer.
Why you want this marketing to be based just on Twitter?
I can provide you with Twitter, Facebook and LinkedIn based marketing.
Why you need this to be manual job?
I can make script that will do something like this.
It will create many accounts on each social network.
It will post different messages on each tweet or post.
It will store URL to the page where is tweet or post made.
I will make basic website, so you will have good looking front end, to search all posts made, there content, and links to that pages. There I will make text field where you can save your text for post.
You can place that text on every account, or you can save many posts, and make script to run randomly.
That will be local website, will run local, and I will concentrate to make good functionality, not good looking.
Also, I can make scripts to search your concurents.
So you will have everything you need, for good marketing campaign.
Also you can provide me with some URLs to websites, where people promote there books, and I can make scripts to place anything you want.
Please message me, so I can write more in this proposal bid, because I don't have any more characters left.
Best regards,
Sasa Sekaric
