So as the title says I need a freelancer who is able to post at least 2 comments daily and thumb up them so that they stay among the most popular comments. You should also track if the comment has been deleted or rated as spam.
I'll give you the basic body of the comment upon rewarding for a bid and you should spin the comment so that it won't be deleted so easily.
At first, I'll hire you for a week and if you do the rating well enough I would hire you even for a longer time.
And final note, I assume your working time is 1 hour/ day so everyday you'll earn a pay for an hour.
