Did anyone has some experience with paid freelance beta readers from that website? I gave my manuscipt to some with excellent opinions (and supposed graduated writing class). But they claimed that they enjoyed my book and there is very little to improve. I know there is plenty to improve (bah, no book is perfect) and I just feel that they are too affraid to share honest review. Some people don't have thick skin, so I understand that those betas don't want to risk thier reputation or money return.
