[I] have been looking for a freelancer who can meet my requirement level. I paid [a lot] of money to find a good freelancer, most of freelancers that i tried were not at my required level, i believe that my subject is really hard. The best one i have ever met here is Rachael. She cares for every single point, digs the content very well, then she gives you a suggestion after the discusion with you. Timing is always good.
