Ok, on my next assignment I have 160 questions for human resourse management, do I have to make a new post? and what do you want total price with bonus?

Expert:  FiveStarLaw replied 3 years ago.
That sounds great!

You are required to open a new post – site rules. \$200 total, 160 bonus and 40 to the site when you open the question would be fair.
