cheapest automatic retweets and likes?

who provides the cheapest automatic retweets and likes?

if i want each of my tweet to get 100 retweets and 100 likes, and i post 50 tweets a day, what would be the monthly cost?

i am NOT talking about panels.

I would like to know this too. automaticretweet.com offers likes and retweets but it says "*up to three 10 tweets per day, can be automatically retweeted up to 1,500 times."

I don't know what "up to three 10 tweets per day" means. I need retweets on all tweets per day.
